Florence Perret

Welcome to Florence Perret. She will do at least a one-day-a-week internship during the first term. She might decide to stay longer.

« As a history student on my second year of Master degree at the University of Paris- Saclay/Versailles-Saint Quentin, I am currently working on a Master thesis that focuses on the consumption of exotic goods in 18th century Versailles. Considering the theme of this Master thesis, this internship is a real chance for me to learn the basics of academic research in an area that matches my personal interest. Even though my own research is mostly dedicated to social and cultural history, this experience is an opportunity to consider the external commercial trade of 18th century France, and thus, a possibility to familiarize myself with economic history. But, more importantly, this internship will provide me a familiarity with necessary tools and methods such as the creation of a database or the classification of terms and items. This knowledge will be particularly convenient as I consider continuing my research in the following years. I really hope my participation will also benefit TOFLIT18 and help managing the information contained in the database. »

Location: Sciences Po (Paris)

Marc Badia, Leslie Bermont, Bertrand Blancheton, Ana Carreras Marin, Léo Charles, Loïc Charles, Guillaume Daudin, Béatrice Dedinger Michel Fouquin, Pierre Gervais, Paul Girard, Michael Huberman, Jules Hugot, Wolf-Fabian Hungerland, Ragnhild Hutchison, David Jacks, Aidan Kane, Thomas Le Roux, Ivan Ledezma, Pierrick Pourchasse and Jan Willem Veluwenkamp and several students.

Short welcome introduction by Guillaume Daudin (local organizer)

1st paper:

Making historical international trade data useful (Germany, 1880-1913)
Presentation by Wolf-Fabian Hungerland (Humboldt-Universitat zu Berlin)

Wolf Fabian discusses the use of the German source and how the goods therein can be classified. Source volumes are disparate: different number of year per volume, number of categories and classification different. This is what it is very useful to use a SITC classification.

Then, he opens a discussion on the matching issue (how to find a SITC equivalent to the original product as it was labeled in the source volumes), utilization of SITC 4 was privileged. Results are encouraging so far.
Object of the database: study the extensive margin over the long period.

2nd paper:

Standardization of Latin American trade statistics. Sources and methodology for a study on the diversification of export baskets
Presentation by Ana Carreras Marin (Universidad de Barcelona).

Ana Carreras discusses the industrial and geographical diversification of Latin America’s trade c. 1913. There is Trade-off between standardization and the specificity of the economy one is analyzing.
Research issue : multi-goods partners in extensive / intensive margins.
There is a discussion around whether it is a good idea to use the SITC classification?

3rd paper:
Domestic Barriers to International Trade: New Evidence for Brazil, 1920‐1940
by Michael Huberman (Université de Montréal)
In his paper, M. Huberman addresses the issue of the relationship between coastal domestic trade and international trade. Was the former a substitute for the last, or was it part of an educational process of the entrepreneurs that subsequently became exporter ?
Research issue : the study domestic trade in parallel with international trade.

3rd paper:
Custom 15: Constructing a database of Ireland’s international trade 1698-1784
Presented by Aidan Kane

Data capture and cleaning of trade data for each year 1698-1784 is now essentially done, and will be soon generally available. Data typically distinguishes six or seven major trading areas. The data are available for around 25 Irish ports, in each year, and the originals are remarkably consistent in format over the time period. Aidan underlines the small number of commodities (500s). 140 volumes of ledgers digitized over the period 1698-1784. Exports much less precise than imports
They did the arithmetic checks automatically
Right now, no classification but he is looking forward to use SITC.

4th paper:
English/British/UK Trade Statistics 1700-1899
Presentation by David Jacks (Simon Fraser University and NBER)

1 out of 10 years digitized. Around 130,000 raw observations (100,000 in SITC). Looking at gravity (distance versus empire)
Problem of prices (resolved at an aggregated level by indexes)
Names of commodities normalized into the database (original spelling not retrievable)

5th paper:
Choosing a Product Nomenclature: The French Case 1836-1938
By Bertrand Blancheton
Working on « commerce spécial » (without transit trade)
The impact of tarifs on specialization ? Choice of classification : SITC versus ISIC ?

6th paper:
The Norwegian customs project- classification and standardization – a practical solution?
By Ragnhild Hutchinson (University of Oslo and Norwegian Institute of Local history)

27 ports for 9 years from 1686 to 1835. The project tried 4-digit SITC and the 1870 classification, but it did not work out : too much time and the match was no good (classification too modern).
This no classification so far, but she wants to implement a suggested classification option as in Navigocorpus.
Funding obtained mostly through private donors, but it constrained the project somewhat: short-term funding renewed several times and for teaching rather than research purpose.

7th paper:

Sound Toll Registers Online, 1497-1857. Standardisation and classification issues.
By Jan Willem Veluwenkamp (Groningen)
Again, the difficulty of using a precise SITC category is apparent.

8th paper:

Your ‘goods’ are not my ‘products’; a preliminary methodological discussion of our instinctive belief in the permanence of things over time and of its unintended consequence
by Pierre Gervais (Paris 3 Sorbonne Nouvelle)
Argue that the main difficulty that arise with any classification of the trade of traditional economies is that it had to cope with commodities that are to a large extent unique for each local context (an ‘indienne’ in Bordeaux in 1726 might not be the same an ‘indienne’ in Marseille in 1726 or an ‘indienne’ in Bordeaux in 1756, etc.)

Wrap-up session :
Guillaume Daudin presented the datascape methodology and how it was applied in the TOFLIT18 project to manage the French balance of trade dataset. Then, he moved on to show some preliminaty results and how the visualization of the relation between commodities illustrates how La Rochelle changed from a port with a diversified set of exports in the 1720s to a much more specialised one in the 1780s.

Loïc Charles gave some concluding remarks. Suggest that they are two different strategies to build a trade database : either to digitize the data and try to save up as much as you can or try to simplify. The latter was the only option available before the IT revolution of the 2000s. But now, it is of the utmost importance of keeping everything in the database.
Second point : You do not have to define a classification ex-ante. Quite the contrary, the philosophy of the datascape is to have a tool that allow the ex-post creation of several classifications in a relatively short period of time (a few weeks). The argument is that each research issue requires more or less a different classification : if one wants to work on an historical issue, it is better to use a classification close to the sources, while SITC is better for long period studies especially when comparison with 20th century is wanted.
Finally opens a discussion on a possible convergence at a European level, through an ERC project.

Septembre 16th 2016 Workshop «Classifying trade statistics before 1945»

Chers collègues,

J’ai le plaisir le vous informer de la tenue d’une journée de travail « Classifier le commerce international avant 1945 » à SciencesPo Paris (salle Goguel) le 16 septembre 2016.

Vous êtes tous cordialement invités. Pour des raisons de sécurité (et pour que nous sachions combien de plateaux-repas commander), merci de vous inscrire auprès de Biljana Jankovic biljana.jankovic@sciencespo.fr.

Sincères salutations,

Guillaume Daudin



Classifying international trade before 1945

Classifier le commerce international avant 1945

September 16th 2016
Salle Goguel, SciencesPo, 27 rue Saint Guillaume, 75007 Paris

The long history of globalization is blessed with a comparative abundance of data. Foreign trade has long been a sizable source of income for states and the latter have been careful in collecting information on it: series on international trade starting in the eighteenth century exist for several countries and regions such as England, France, Sweden, the Austrian Netherlands, Venice, Portugal, Spain. (Charles et Daudin 2015). The Sound records go back even further. Hence, much information on past economies may be gained through the systematic collection of these data. This calls for the creation of large databases and there are a number of active projects, under different states of readiness: Ireland, Norway, UK, World, France, Germany, the Sound… The identification and classification of commodities is at the core of any project that want to use these databases for comparative analysis or even to simply use the information collected to its potential.

For example, in the French case, there are more than 45,000 different merchandises mentioned in the 18th century sources (for 400,000 trade flows). Correcting for mistakes made by the original scribes and the person in charge of the transcription brings that number down to 20,000. Further identifying synonyms brings it down to 16,000. It is however necessary to devise some sort of aggregation process to be able to use the data collected to answer a wider set of economic history issues such as those linked to the question of trade diversification, intra-industry trade and revealed comparative advantages.

An additional difficulty is international comparison. There are more problems linked to it than the sole issue of translation. The creation of internationally comparable merchandise classification was a long process starting only in the late 19th century (Kolesnikoff 1953) and it is still a work in progress. Yet, it is central to any comparison process.

Choosing a classification to categorize commodities should meet several criteria: it has to be informed by past practices of recording flows (which are different from one place and one time to another), the characteristics of the past society/economy where trade took place, convenience (as classifying goods is hard work), and the research issue. Among the possible options are: 1. the adaptation of modern nomenclatures, which have a great level of detail, accuracy and comparability, but hardly relates to the economic issues of past societies; or 2. the creation of a tailor-made historical nomenclature, which takes into account the historical context of commercial exchange but begs the issue of intertemporal (and often geographical) comparisons. Moreover, creating a nomenclature takes a lot of time in particular if one wants to produce disaggregated categories. A flexible system of classification that can be integrated in data exploration in order to be able to create detailed categorization for specific purposes within a reasonable amount of time and resources would be ideal. But that requires to invest a substantial amount of work in the creation of sophisticated digital tools, as endeavored by the project TOFLIT18 (http://toflit18.hypotheses.org/).

Ramillo Parungao

Bienvenue à Ramillo Parungao, qui nous rejoint milieu juillet pour un stage jusqu’à début septembre.

Ramillo a intégré l’école de commerce ISC Paris après deux ans en classe préparatoire Technologique. Il souhaite se spécialiser en Marketing Digital.

Il a intégré l’équipe du projet Toflit18 le 18 Juillet 2016 dans le cadre d’un stage de validation de sa première année. Il travaillera principalement à l’Université Paris-Dauphine. Il aura pour mission de faire de la retranscription de documents de la balance commerciale qui concernent les exportations de Nantes entre 1728 et 1779.

« J’ai découvert grâce à ce stage en tant que transcripteur données un aperçu du travail de chercheur. Ce stage m’a apporté certaines connaissances au niveau de l’histoire, du commerce et de l’économie en France au xviiie siècle. De plus, j’ai gagné en autonomie et rigueur, car les données sont précises et doivent  être vérifiées pour vérifier la cohérence des documents.

Le projet Toflit18 m’a permis de découvrir une autre facette de l’économie car mon cursus n’a pas couvert l’histoire du commerce. J’ai trouvé intéressantes les corrélations qu’il y’a entre les différents évènements historiques et leurs influences sur le commerce. »


July 5th 2016 meeting

July 5th 2016 meeting

Attending: Loïc Charles, Guillaume Daudin, Béatrice Dedinger, Frederico d’Onofrio, Meng Ying Du, Pierre Hollegien, Pierre Gervais , Paul Girard, Corentin Ponton, Grégory Tible, Quentin Vidal.,

  1. Ricardo

Following the meeting with Federico and Tena, some changes have been implemented to the datascape: bilateral trade flows and world flows are now separated; the Federico-Tena database has been added in the metadata view where partners can be displayed by color. Moreover, it is now possible to compare the Ricardo’s best-guess with the Federico-Tena’s one in the country view: they largely match except for a period where exports are missing.

The project is to be presented at the digital humanity conference newt week.

  1. Transcriptions

Hasna achieved her tasks: she completed every import in Marseille, and the ones in Nantes until 1761. Requia has not made such good time: about 10 years of exports in Marseille are still to be retranscribed (1741 and 1742 are very difficult to read and are hard to read, Loic will have to deal with them).

Demba is going to complete Bordeaux and will start transcription for imports or export in Nantes.

  1. Verifications

Loïc is still checking transcriptions. There are many difficulties: typos (easy to correct), computing errors, wrong unity of measure (more annoying), etc. Trade records were on average better done in big direction than in small ones. Marseille represents a lot of works (about 2500 lines per year – a big day of work is not enough to deal with one year).

Total sums computed by the copyist does not always match with the ones computed by ourselves, but the later are to be preferred because of the excessive rounding or computing errors made by copyists.

  1. Merchandises

Since 1815, merchandises’ names appear to be much more heterogenous, which increases the work of orthographic normalization and simplification. However, it can be explained by the large number of braces in the products’ labels that are used to distinguish classification and specification.

  1. SITC

Pierre Gervais is pursuing the classification of the goods, but his facing some difficulties due to the state of the “simplification” file. Most problems wil be tackled by an algorithm that does not integrate every spelling yet.

Beatrice proposes to make a unique and universal classification of products from the 18th century. It sounds like an enormous project for the moment though

  1. Datascape

New classifications have been added up to the datascape or updated: Medicinal Products by Pierre Hollegien, North American products by Quentin Vidal, Eden Treaty by Corentin Ponton. The grains’s classification made by Federico d’Onofrio is still to be uploaded. “Revised” classifications are now the standard ones.

Bugs of interface are being fixed, especially when selecting parameters for plotting network views.

Guillaude Daudin asked Paul Girard and Gregory Tible on the possibility to implement a new feature in the datascape. It would consist in a tool allowing us to pick terms from a daughter classification and use them in a mother classification. The mother environment would be filtered by the daughter classification.

  1. Next Meetings

No more TOFLIT meetings before the end of the summer holidays.
Research of a room that could host the 16
th September meeting, and discussion about an accommodation in Chicago for October.


June 8th 2016 meeting

Merci à Corentin et Quentin pour la première version du compte rendu de la réunion du 8 juin.

Guillaume Daudin, Béatrice Dedinger, Meng Ying Du, Pierre Gervais , Paul Girard, Corentin Ponton, Grégory Tible, Elisa Tirindelli, Quentin Vidal.

1)    Retranscription
Imports coming from Marseille are done, but are still to verify.
Marseille’s exports however should be done in two weeks, as well as 1789 sources.
Moreover, Demba will achieve entering Nantes and Bordeaux sources before long
Cyril Canet is doing Rennes and Nantes ones
Quentin Vidal is completing the 1823 Table of Quantities, while Corentin Ponton in entering unit prices from 1819 to 1821.
Since character recognition does not work (even on printed registers), manual retranscription is necessary, even though it is long and dull. Anyway, we really would like to stop it by the end of summer, so as to focus on the database exploitation.

2)    Verifications
1789 is nearly done (only 4 directions are left) 1789, and then it will be over.
For England, 1787 and 1788 still need to be done.
Idem for Marseille’s imports. It is a long job (between 2000 and 3000 observations each year).

3)    Identification of commodities and classification
We are still following the 21th century Standard International Trade Classification (SITC) proposed by United Nations to group the nearly 20 000 goods of the dataset by category. However, Pierre Gervais is facing some difficulties regarding particular products and groups which are completely meaningful nowadays but did not make any sense back in the 18th century.
For instance, he evokes the case of medicinal products that were often considered as food supplies in those days (such as the saffron, which is also used as a dye). Besides, dye plants and tinctures are also mistaken.
Tea is an issue for 0a/0b as it can be both be produced by local farmers or on plantations.
So far, about 20% of the 15 000 goods are classified, although a large part of them goes in “category x” whenever a doubt arises. By the way, a great share of commodities is also labelled as raw materials, which is certainly overestimated. This work should be done by the end of the month.

Furthermore, Elisa’s Hambourg classification is available on the datascape, while Quentin aims at creating a classification for specific Canadian products and Corentin for products impacted by the Eden Treaty

4)    Elisa Tirindelli
Elisa Tirindelli defended her master thesis this week: she tried to explain the effects of war on French exports by distinguishing the effect on colonial exports (sugar and coffee) and non-colonial ones (wine and spirits).
She will pursue a PhD track in Dublin next year in historical and urban economics.

5)    Datascape
Paul Girard and Gregory Trible have improved the performances of the website. They created two new tabs from the “Global tab”: Countries Network and Product Terms. The former is not completely working by now but will display interesting information on countries relationships in trade, while the later could return details on the complexity of merchandises by analyzing every term of each commodity.
The metadata tab has seen a few improvements. However, we would also like to aggregate flows by classification. For instance, we would like to see how the “pays grouping” classification has evolved through the decades so as to understand how Toscane, Piémont and other provinces were assimilated in Italy by the statistics.
Besides, as some particular mixes of criteria do not obviously exhibit any results (since they are completely irrelevant), we should give users more information and advises regarding requests, by the means of help pop-ups or FAQ.

Gregory Tible’s internship is nearly over; he will leave Sciences Po at the end of July. Paul will Guillaume Plique might punctually intervene on the datascape. But Paul will do the main work. The additional budget will be necessary to find some help.

6)    Ricardo
Ricardo is doing well. The team has been chasing bugs and developing the mew Metadata view (issue of mirror rates)
After that, it will be back to data management (eg source cleaning).

7)    Next meetings
•    June 22nd: (Ricardo meeting) with Giovani Federico and Antonio Tena
•    July 5th, 9.30am at the Médialab: last TOFLIT meeting before summer holidays.
•    September 16th – 17th: public meeting with people from the English project, Norway, Ireland and the STRO (7 guests have already favorably answered); internal meeting on Saturday 17th.
•    October 14th in Chicago: need to obtain more details from Loic Charles.

May 11th 2016 meeting

May 11th Toflit meeting
Attending : Requia Bouali, Loïc Charles, Guillaume Daudin, Béatrice Dedinger, Federic d’Onofrio, Meng Ying Du, Hasna El-Adel, Pierre Gervais, Paul Girard, Corentin Ponton, Grégory Tible, Elisa Tirindelli, Quentin Vidal

1. Presentations

2. Retranscriptions
– For Marseille, Requia is doing year 1749 and Hasna 1751.
– Laura is working on 1789.
– By the end of May, we should have most of Marseille + Nantes.
– Demba will finish afterward. We plan to stop in July.
– Corentin Ponton adding some unit values from 1815 to 1821. But they are not bilateral : it seems like there is a double aggregation of values and quantities because computing of average prices exhibits wrong results.
– Quentin Vidal is transcribing post-1815 sources by the customs, that indicate quantities and duties.

3. Verifications
•    Loic Charles is checking the retranscription of Grenoble and England sources (4 to 5 thousands lines a day). He expects to end this job by September.
After summer holidays, we should stop retranscripting of new sources so as to focus on the database exploitation.

4. Identification
– Identification of commodities is nearly done (thanks to Quentin and Corentin); some doubts remain concerning strange words, though most of them might come from foreign languages (Dutch or Flemish mainly). Note that those unknown goods are worth only small amounts.
– We could use Beccia’s information to enhance the identification
– We could identify some Indian textiles because they all end the same way.
– There are copyist mistakes that are very difficult to correct.

5. Identification
Pierre Gervais and Guillaume are working on the SITC variant we will be offering as one of the classifications. We discuss the difficulties.
•    SITC: consists of a dozen of categories, divided into more sub-categories.
o    Motivation: building bridges between different projects and between different centuries.
o    Drawbacks: frontier between categories might be too blurred, and some goods create ambiguities, about the transformation degree for example. There are way too much commodities in the category “9C: other products”.
o    Should we create a new version of the SITC classification, maybe more fitted to our project but less standardized and thus less internationally recognized?
•    Examples of problems encountered during the classification: What to do with some chemical products, such as medicines that are not always transformed products? With textile goods, made of cotton, silk or something else we do not know?
•    Ideally, we aim for a classification perfectly understandable for someone who does not know anything about the project, or at least anything but the rules of the classification.

6. Quantities in the datascape
We discuss how to integrate quantities in the database. Guillaume suggests we could create one variable / facet for each type of quantities (weight, volume, number and maybe length). In that way, they could be treated like values in the datascape.

7. Work on the datascape
We have a quick discussion on progress of the datascape, and how to treat 1749 and 1751 for National Best Guess

8. Ricardo
We admire the new version of the Metadata view.

9. Next meetings

•    June 8th 2016 (Toflit meeting), at 9h30, Medialab.
•    June 22nd  2016 (Ricardo meeting) with Giovani Federico and Antonio Tena
•    July 5th: last meeting before summer holidays.
•    September 16th : public meeting with people from the English project, Norway, Ireland and the STRO. There will be an internal meeting on Saturday 17th.
•    October 14th in Chicago (financed up to $4500 from Chicago side). It would be nice if Pierre, Paul and Siliva could come.

Hasna El Adel

Bienvenue à Hasna ! Elle nous a rejoint pour former une équipe avec Requia.

Hasna est  actuellement en première année de master Économie des organisations, option Management de Projets Publics et Privés à l’université Paris 8 à Saint-Denis. Elle a préalablement obtenu un diplôme de licence Economie-Gestion dans cette même université en 2015.

Elle a intégré le projet TOFLIT18 le 4 avril 2016 dans le cadre d’un stage de 3 mois, où elle est rattachée à l’Institution National d’Études Démographiques. Elle a  pour mission de faire la retranscription des documents d’importations des villes de Marseille (entre 1726 et 1759) et de Nantes (entre 1731 et 1761).

« Dans le cadre de mon stage, je vais analyser la question du financement d’un projet de recherche (notamment celui de TOFLIT18) et des procédures mises en place pour le dépenser de manière efficace par rapport aux objectifs scientifiques de ce(s) projet(s). Je participe de manière plus générale aux activités administratives du projet, telles que les réunions mensuelles.

Ce stage est une manière pour moi de découvrir le secteur public, qui m’était jusque-là inconnu car n’ayant eu que des expériences dans le secteur privé. De plus, c’est une initiation au monde de la recherche que je ne connaissais pas. »


Requia Bouali

Bienvenue à Réquia dans l’équipe !

Réquia Bouali a intégré le projet ANR TOFLIT18 dans le cadre d’un stage d’une durée de 3 mois. Elle effectue principalement la tâche de retranscription des documents de la balance commerciale de la Direction de Marseille pour les années 1726 à 1780.

« J’ai toujours été fascinée par le travail des chercheurs, notamment en science sociale. C’est d’ailleurs la raison pour laquelle je me suis intéressée à la recherche. Ayant effectué une licence de sociologie à l’université Paris 8 Vincennes Saint-Denis, je me suis ensuite spécialisée en anthropologie. Je fais également, en parallèle, un second master. Il s’agit du Master Économie et Management des Projets Publics et Privés.

Je vois à travers ce stage le moyen de me familiariser, d’une part, avec le monde du travail dans une institution publique et, d’autre part, celui de répondre à certains de mes questionnements relatifs à la vie de chercheur. Cela me permettra de mieux définir mon projet futur qui est de poursuivre à terme un travail de thèse.

Participer à la réalisation du projet TOFLIT18, me donne envie de donner le meilleur de moi-même et me procure un sentiment de fierté. En effet, l’ampleur du projet, mêlant à la fois l’histoire, la géographie et l’économie en France dans le XVIIIe siècle, me permet de découvrir des facettes multiples du travail de chercheur. »




Quentin Vidal

Welcome to Quentin Vidal! He is a student at TSE who will work with the project from April 18th to July 13th. He is currently working on identifying unkown goods in the database (we have nearly 1,200 definitions in our glossary).

« After four years of university education in the Toulouse School of Economics focused on macroeconomics, history and development economics, I now have to seriously consider my professional plans. Thus, this internship should constitute my first approach of the world of the academic research, a field that intrigues me as much as it interests me. Those three-months of observation and work among a research team offer me the opportunity to discover a multi-disciplinary project, involving historians, economists and data scientists all connected by means of some useful, powerful and productive online tools. The thoughtful building of such a large and essential dataset and its subsequent analysis are very challenging aims; both of them require a great curiosity for this historical period, which perfectly matches with my interests. I hope I will be able to add my contribution and am really looking forward to assisting this project. »


Quentin Vidal CV

April 13th meeting

Réunion Toflit 13/04/16

Requia Bouali, Marie-Laure Dagieu, Guillaume Daudin, Béatrice Dedinger, Hasna El-Adel, Paul Girard, Laura Mouton, Grégory Tible, Elisa Tirindelli, Du Meng Ying,

1) Interns
The project is presented to out two new interns : Hasna El-Adel and Requia Bouali. They are working on the retranscription of Marseille and Nantes. We discuss how to use the datascape to facilitate the retranscription

3) Budget
INED has 35,000 € left. We expect to spend approximately 20,000 € this year. At the end of 2016, 80% of the initial budget will have been spent, mainly on wages and contractors.

Sciences Po has 25,000 € left at the end of 2015. 60% of the initial budget has been spent, mainly on wages. After Guillaume Plique and Gregory have been paid, we will have approximately 10,000 € left. We discuss whether we want to transfer this money for other workers in 2017.

Dauphine has 70,000 € left. Only 15% of the initial budget has been spent. This is because Dauphine will mainly take in charge missions and conferences, which will be more important at the end of the project when we will be able to present the data and our research results. We are late in the collection and organization of the data.

4) Datascape
Pierre Gervais is currently working on the SITC classification.

We discuss the chronological repartition of good names. Only roughly 10% of products are mentioned every year, suggesting that semantic variations are very important.

Paul Girard is working on making updates to the datascape easier so that they can be done regularly.
Gregory is working on improving the interface and squashing bugs. For exemple, the server breaks down under searches crossing countries and goods in the indicator visualization.

There is still a bug when trying to search by crossing simplification pays and direction.

5) Ricardo
The source names have been nearly fully streamlined.

Du Meng Ying is working on a new « metadata» visualization. It  shows which data are available from which place: they can be sorted by number of flows in the whole period or by average value of flows.
We discuss the use of absolute value of trade or share for sorting purposes. It would be better to calculate average value as average of the share of what is available, to avoid countries with trade only in 20th century to stand out just in value terms.

Each main viz will have a metadata equivalent. This is done for the Country and the World view, but not yet for the Bilateral view.

6) Meetings
Next meeting is May 11th at 4pm at the médialab 13 rue de l’Université. We discuss our schedule for the end of June without reaching a definite solution.

Transformations of the french economy through the lens of international trade, 1716-1821
