“Improve research opportunities and outcomes through linking distributed digital source materials of many kinds”

http://www.dariah.eu/

� For contributorsTo give visibility to their contributions

� For researchersTo give them tools to find relevant information

Objectives

2

� Who are experts on Open Archive?� Who offers a PID service?� Who works on Alexandrian pottery, 2nd century B.C.?� What are the available collections on archeology?� What is the procedure to obtain the DSA?� What are the recommended formats for images? � What are the Dutch contributions?� Is Jean-Luc Minel involved in Dariah?� Is the INA (Institut national de l’audiovisuel) involved in

Dariah?� Which European projects are related to Dariah?� etc.

What could be relevant questions?

3

� To deal with decentralized dataEach contributor is responsible for the description of his contribution

Each country is responsible for gathering and displaying the contributions

� To use standard toolsTo use languages of the Semantic Web (RDF, SPARQL)

� To exploit Linked Open Data possibilitiesTo use existing data from other repositories

� Low cost and time investment

Example of RDFa Annotations

<!-- la description du contenu de la contribution --><meta property="dc:subject" content="type d'offre : Accès" /><meta property="dc:subject" content="DARIAH" /><meta property="dc:subject" content="Linguistique" /><meta property="dc:subject" content="Histoire" />

<meta property="dc:subject" content="VCC3" /><meta property="dc:subject" content="Corpus journalistique, Presse Régionale, PQR, XML - TEI P5, TEI P5, Est Républicain, Productivité" />

Answering relevant questions

PID assigned by ISIDORE if necessary

Automatic enrichments using thesaurus and skos relations10

A very smart HCI

Some milestones

� How long to make annotations using RDFA ?

� Between 15 or 30 mn by contributions (depending on who make it and the accuracy of the metadata)

� How long to develop a crawler ?

� No need to develop a crawler. ISIDORE exists and is available (French contribution in Dariah). Of course, it is possible to use another crawler.

� How long to build a triplestore?

� Few hours using a private or public data center. It is not required that each country builds a Tstore.

� How long to develop simple HCI ?

� One day by an agile digital humanist. Of course, HCI can be share18

Flexibility and Responsibility/Best practices

� Dariah.eu can display all contributions on its website

AND

� All partners can display and expand all their contributions with their own choices (VIAF, IDREF, Geonames, Pactols, etc.) and with their own interfaces

***

� As all partners describe and expand their contributions, they are responsible for their visibility... which is also a best practice

19

Some issues

� Contributions in English

� “Standardisation” of the description of the contributions (proposition of a template)

� Choice of vocabularies

Dcterms, foaf, skos, bibo

� Taxonomies, ontologies and thesauri

Ex.: NeDiMAH ontology, Rameau, Geonames, etc.

Existing, simple and but not perfect!

20

Some issues

Linked DataHow to exploit data from other triplestores?Which ones ?

Social Network?

21

In a nutshell

� Each partner manages its contributions and displays them on a webpage of a website� Each webpage is annotated with RDFa, following some

guidelines (using common tags and vocabularies)

� Dariah.eu (and/or Dariah.Anycountry) harvests these websites regularly and puts all the harvested data in a triplestore

� Dariah.eu and/or Dariah.Anycountry offer simple tools to peruse all these data

� Anyone can search in the triplestore using Sparql queries

� Visibility, simplicity, interoperability
