R&D Agenda

Network

Product Development

Foster a network of specialists from GLAM and research institutions, who can advice on technological topics when needed

Develop R&D agenda for Europeana: identify trends & gaps, who is working on them, how we can support them

Feeding R&D results from the scientific / open source community into the development of Europeana

Informing IT-related networks, e.g., the Linked Open Data or Digital Libraries communities, on Europeana-related R&D. disseminate our partners’ technological advances

The EDM model is improved and incrementally updated

Tasks

Supporting project: Europeanav2.0 WP7

Tasks

Developers' Network

Development of innovative applications for user interaction and UGC

Semantic Web / Linked Data

Multilingual Access / Translation

Supporting network: EuropeanaTech

DevelopersCurrently:• Persistent Identifiers• EDM and FRBRoo• Hierarchies

This period: • FLOSS inventory

Next period:• Software development

EuropeanaTechCommunity

From MS37 Mission Statement:

"The mission of the EuropeanaTECH community is to gather task forces on specific technical points (metadata display issues, extensions to the Europeana

Data Model, etc) and foster a Europeana Software Developers Network”

Task Forces

http://pro.europeana.eu/web/network/europeana-

tech/

Output 1: Inventory of FLOSS in the Cultural Heritage Domain

Already 85 entries!

Already 85 entries!

Output 2: Market study on semantic feature extraction

Tools for the extraction of concepts and named entities

Basis for decision-making for Europeana

Available on EuropeanaTech Wiki as living document

http://pro.europeana.eu/web/network/europeana-tech/-/wiki/Main/Market+study+on+technical+options+for+semantic+feature+extraction

Two example foci: EDM and multilingual issues

Focus: EDM status

Focus: EDM status

First implementation

• Provided Objects, Web Resources, Aggregations, Agents, Concepts, Places and TimeSpans

Documentation

• Definitions, Primer, Mapping Guidelines, Object templates, XML schema, RDF/OWL ontology

Prototyping ingestion with partners

• CARARE, MIMO, HOPE, CulturaItalia

Pilot export ESE->EDM as part of data.europeana.eu

Ingestion chain ready in October

Focus: EDM next steps

Assessing input data and processes with partners• Getting mappings from original data to EDM

Validate existing choices of properties

Propose refinements or extensions

Adapt data dissemination channels to interoperability needs• Facilitate re-use of Europeana metadata by partners and third-parties

Focus: EDM next steps

Metadata enrichment

Linking objects to contextual resources• GeoNames, VIAF, domain-specific thesauri

Linking contextual resources• Thesaurus alignment

Linking objects• Clusters, FRBRization

Focus: EuropeanaTech EDM task forces

Model refinements on EDM

Task force on Hierarchical Objects

Task force on EDM-FRBRoo Application Profile

Focus: multilingual issues

Multilingual display, retrieval and interactions are not commonly implemented in CH websites

• State-of-the-art analysis of 50 cultural heritage websites

Dimensions of multilingual access

Interface

Search (query translation or document translation)

Result presentation

Browsing

Europeana's efforts

Interface translated into 26 languages

Query translation: only prototype

Query result filtering by country/language

Document translation (user enabled)

Semantic contextualization of objects

• Multilingual enrichment/annotation of metadata

Multilingual foci

Focus on educating community• Multilingual dimensions and effects on display and retrieval

• Multilingual handling in EDM and ESE

• Ingestion of multilingual contextual resources (thesauri etc)

R&D: better use of language resources• Natural language processing

• NB: some of “our” resources (thesauri etc.) are also language resources!

Multilingual and semantics can go hand-in-hand

Fetching available linked data

http://www.w3.org/2005/Incubator/lld/XGR-lld-vocabdataset/

E.g., from libraries

Interoperability

Encouraging the use of RDF + common and simple elements

Interoperability

Encourage the use of common and simple data elements

Multilingual Access: users back in the loop

EuropeanaTech: lessons being learnt

Need for active community support• Highlight the added value to contribute to EuropeanaTech

• Actively disseminate outcomes

• Reach out to the wider community

also outside de EU!

Need to actively manage task forces:• Define stort-term, measurable goals

• Provide communication support

• Tasks are interleaved and should inform each other

How to contribute?

Several levels: organization, advice, code, data…

Become a member of the EuropeanaTech community

• mailing list, twitter…

Designate a "technical/R&D contact point" in their project?

http://pro.europeana.eu/web/network/europeana-tech/

How to contribute?

React to our deliverables

Contribute prototypes & demos in ThoughtLab

Contribute deliverables & software to mindmaps

• semantic technology

• should we create other mindmaps?

Contribute documented EDM metadata and mappings for next steps of EDM

Participate our coming meetings

• how about a joint technical meeting in 2013?
