PROPOSAL FOR AIMS and strategy of the EUROCRIS Linked open data Task group (LOD-TG) Meeting at Bath (UK), 10th February 2012
Contents • A (very-)short history of the LOD TG • Proposed LOD TG aims and objectives • The CERIF LOD recommendations • Plan for 2012 • Main deliverables • Outlook
LOD TG antecedents • 25th May 2011: EuroCRIS membership meeting at Bologna hosts a joint workshop of EuroCRIS and the VOA3R project (http://voa3r.eu). • VOA3R presented its implementation of CERIF 1.2 on a social network context and combined with an aggregator of scholarly content metadata. • The workshop includes discussion on issues about implementing a LD prototype in VOA3R. • July 2011: Informal meeting of EuroCRIS members and technical team of VOA3R • Discussion on key changes required in CERIF • Presentation of a proposal for a mapping approach implemented in VOA3R. • December 2011: LOD TG starts activity.
Aims and objectives • Aim: Leveraging Current Research Information System (CRIS) data by exposing it through Web technology so that it can be interlinked and become more useful. • Objectives: • Elaborating use cases and scenarios that show how the LD approach may solve problems of different stakeholders. • Analysing the regulatory and ethical issues associated with CERIF LD and the scenarios for sharing LD openly or with restrictions. • Producing recommendations to expose CERIF data or CRIS data in general as LD. • When required, informing the CERIF TG of potential changes in the CERIF model that may improve the utility of CERIF LD exposure. • Supporting the hosting of CERIF-based LD vocabularies in the EuroCRIS infrastructure. • Creating and maintaining mappings of the CERIF LD vocabularies to other vocabularies and/or ontologies. • Promoting the adoption of the LD approach by vendors and institutions in general.
The CERIF LD recommendations • A document + a prototype implementation • Separating the use cases to another document • 2012: Limited to CERIF 1.3 • Focus on an easy transition/extension of existing CERIF deployments. • Divided into modules: • Base, core mapping of CERIF entities. • Recommendations for linking to bibliographical information. • Optional modules: for advanced uses or experimental features.
Proposed working principles • The LD recommendations adhere strictly to the semantics of the CERIF version considered. • “Open world assumption” interpreted as “LD datasets offer an incomplete view on the entities”. • It is assumed also that there is redundant (and maybe inconsistent) information on the same entities on the Web. • Enrichments using additional ontologies or mappings go to optional modules. • to keep the core implementation clear to vendors and stakeholders. • Linking to other LD datasets are presented as suggestions, not implementation requirements. • Integration via linking with institutional repositories (Drupal, eprints, etc.) is a key requirement.
Plan for 2012 • Activities per objective: • O1: Produce a “CERIF Use Cases for L(O/C)D exposure” • O2: Study the technical and managerial challenges of Linked Closed Data (LCD) • Cobden et al. (2011). A Research Agenda for Linked Closed Data. Proc. of the Second International Workshop on Consuming Linked Data (COLD2011) • O3: Producing the “Recommendations for exposing CRIS data using the CERIF model” covering CERIF 1.3 (excluding full bibliographic information) and creating an associated Drupal 7 prototype implementation • O4: Having continuous communication with the CERIF TG. • O5: Preparing an install of the vocabularies, maybe based on Neologism. • O6: Creating the CERIF-VIVO mapping. • O7: Presenting the LD approach at EuroCRIS meetings and offering vendor-related information on the Website.
Mapping VIVO and CERIF • Mapping at the level of the models – so involving the CERIF TG. • An official mapping can be provided at EuroCRIS website. • Import/export facilities are to be built in the context of FP7 project agINFRA.
Coordination procedures • Document owners: responsible for the update of each of the documents: • CERIF Use Cases for L(O/C)D exposure • Recommendations for exposing CRIS data using the CERIF model • CERIF-VIVO mapping • Open discussion in EuroCRIS lists. • Formal proposals sent to document owners and discussed and eventually voted in teleconferences. • Technical activities will be supported by VOA3R and agINFRA tasks. • Additional contributions with developer or IT staff effort are welcome.
