DM2E All-WP-Meeting 2 November 30, 2012

Vienna

Agenda

1) From EDM to DM2E2) EDM: Definitions and Examples3) DM2E specification of the EDM

− Working approach− Class and property extensions in DM2E− Namespaces, Download and Documentation

4) Wanted: A new name for our specification5) Outlook

DM2E Project Meeting: EDM specification for DM2E 230.11.2012

From EDM to DM2E

• Our starting point: EDM v53, 23.01.2012

– Latest OWL representation of the EDM– Classes, properties and descriptions

• DM2E specificationDM2E v0.1, 22.10.2012

– Additional classes and properties– Deletion of unneeded properties– Adjustment of property descriptions

DM2E Project Meeting: EDM specification for DM2E 330.11.2012

Europeana Data Model

Issue: There is not only one EDM definition...1. PDF documentation (“paper version”)

– EDM Definition v5.2.3– EDM Mapping Guidelines v1.0.1

→ http://pro.europeana.eu/edm-documentation

2. OWL implementation– EDM v53

→ http://europeanalabs.eu/browser/europeana/trunk/ROOT/src/main/ webapp/schemas/edm/rdf/EDM-v523-120123.owl

DM2E Specification v0.1

• Goal: Creation of an EDM specification for manuscripts

• Based on Deliverables 1.1 and 2.1• Extends the EDM by new classes and properties• Makes the model easier by deleting properties that are

not relevant in DM2E

DM2E Project Meeting: EDM specification for DM2E 730.11.2012

DM2E specification

How was the EDM extended?• Results from mapping workshops with

SBB, MPIWG, UIB– Extension requirements of all providers:

– Intellectual mappings for MAB 2 and TEI:→ https://docs.google.com/spreadsheet/ccc?key=0AnNwow7J1RwmdE00

• Ingestion of other provider feedback (UBER)

DM2E Project Meeting: EDM specification for DM2E 830.11.2012

DM2E specification

• Namespaces:– http://data.dm2e.eu/schemas/[edmplus]/0.1/– http://data.dm2e.eu/data/

• Missing features:– External vocabularies are still missing

(except some BIBO properties)– Versioning and Events need to be modelled

Connection to EDM

DM2E Project Meeting: EDM specification for DM2E 1030.11.2012

„We expect that many providers, while submitting data toEuropeana, will be interested in submitting descriptions that fit theirown specific level of interest. The key to ensure interoperability atthe semantic level is mappings, following common practice in theSemantic Web framework.

[…]

Such mappings are typically achieved in RDF by asserting semanticRelationships between the specific constructs and the core ones. Those can take the form of statements usingrdfs:subClassOf or rdfs:subPropertyOf.“

Next steps

• Include input of ONB, NLI and EAJC • Further development: Versioning and Events• Interlinking with other vocabularies

– bibo:Manuscript unpublished document draft– fabio:Manuscript not intended to describe– dm2e:Manuscript a handwritten manuscript

→ First stable release of the DM2E specification in April 2013!
