Availability measures
Permanence measures
Format measures
- articles- monographs- data- softwareetc.
- Creative Commons- free to read- free to mine- embargoed and embargo length- pay-walled
Lots of different ways to measure availability. Examples:metadata quality,discoverability,crawling,machine readability, links to other resources, public access to usage data
Official certification- Yes- No- No but committed to long-term preservation
Per file formats (e.g., PDF, PDF-A, HTML, embedded figures, tables, csv, xls, json, xml)

Open data gov monitor, an example
From OA to Open Science•Free to read? Not enough any more… TDM is around the corner!
•Publications only? How about research data, software, methods…
•Publishers vs. researchers? More stakeholders have entered the game, from funders to the public…
•Reproducibility with OA to research results? Openness is about all phases and processes of the research lifecycle…
•Use and share data via downloads? Think of data driven science and big data analytics…
Need to think in broader terms

OpenAIRE Subsystems and Workflows
• Aggregation• Collection (and validation) of metadata and corresp. Fulltext; multi-
protocol; • transformation into uniform structure and semantics
• De-duplication• Identification of duplicates of objects from same entity type (e.g.
publication, author)• Generation of a disambiguated information space based on sets of
similarity relationships of pairs of duplicated objects• Information Inference
• Applying mining algorithms on information space graph and fulltexts• Inferred information to be used to enrich information graph
• Data Publishing• Population and Enrichment of the information space graph• Publishing over different back-ends: fulltext-index, OAI-PMH,
Statistics-DB, LOD

How do they work?•Identification of Open Access and funded research results by OAI-Sets:
•‘openaire’ for publications•‘openaire_data’ for research datasets
•Latest schema guarantees backward-compatibility with previous versions.•Complemented by metadata enrichment thanks to OpenAIRE’s text-mining
services.

OpenAIRE OAI-Set• To group metadata relevant for OpenAIRE
• See https://www.openaire.eu/content-acquisition-policy/content-acquisition-policy/content-acquisition-policy
• Metadata about Open Access Publications• Metadata about Publications funded in EC-FP7 / H2020• Metadata about Publications funded by other funders

CONTINUE TO BE DEVELOPED OpenAIRE guidelines
to establish an open and sustainable scholarly communication infrastructure
43
New paradigm – global harmonization
1.Extending Dublin Core with qualifiers but without loosing DCMI compatibility
2.Replacing Dublin Core by DataCite metadata schema only
3.Replacing Dublin Core and adopting RIOXX only
4.Defining an application profile based on DataCite plus dedicated elements from MODS (to express the bibliographic citation)
5.Defining an application profile that isa. backward compatible (when possible)b.re-using existing standards (when possible)c. extensible for specific needs
Exploration of best strategy / method / metadata schemes
Proposal metadata Layers
Application Profile that defines
●basic layer (still Dublin Core)
●enhanced layer (re-use DataCite)
●extended layer (custom fields specific for regional networks / infrastructures)

1. Register your repository in OpenDOAR / re3data * institutional/thematic repository -> OpenDOAR * data repository -> re3data
2. Test compliancy with OpenAIRE GuidelinesMake your repository OpenAIRE compliant –>by help of the OpenAIRE validator service
3. Add your repository in OpenAIRERegister your repository in OpenAIRE; pre-filled information imported from OpenDOAR or re3data
1. Registration in Repository Dictionary• For literature repositories use:
OpenDOAR (http://opendoar.org/ )• For research data repositories use:
re3data (http://re3data.org )• If you are already registered in OpenDOAR:
•Check if the information is up to date•Take care on admin email contact and

Scenario•OpenAIRE aggregates metadata about publications from hundreds of
repositories, aggregators, OA journals, and publishers• OpenAIRE guidelines: DC fields + access rights + funding projects + links to
datasets or publications
•Infers information about publications• Relationships to projects and datasets, citations, similarities
•Find duplicates of metadata records for the same publications and merges them to build a (possibly richer) representative record
75
Idea•Institutional repositories may be interested to acquire metadata records of
publications that are “related with” the repository, i.e. they should/could be part of their collection• Enrichment: enrich the records they already have with extra metadata
information• Addition: add to their collection records they were unaware of

Event (potential notification):• Message• Topic• TargetRepository• Trust
The Challnge•Enrichment is straightforward
•Harvesting from repository and return to repository only records that have been “enriched” by deduplication and/or inference
•Addition is less obvious•Based on relationships, in turn identified by inference algorithms•Must be augmented with notion of “trust” to enable “tuning”
options in order to reduce false positive notifications
78
Examples of enrichments topicsENRICHMENT•dc:rights: dc:rights is present and original record was missing it•dc:identifier-if-DOI: DOI is present and original record was missing it•dc:type: dc:type is present and original record was missing it•dc:subject: dc:type is present and original record was missing it•rel-to-project: relationship to project is present and original record
was missing it•rel-to-dataset/software/similar-publication: relationship is present
79
Examples of additions topicsADDITIONS
• authorAffiliation: The publication has an author whose organization has a given institutional repository of reference
• sharedProject: The publication has been funded by a project whose participants (orgs that are beneficiaries of the grant) have a given institutional repository of reference
• authorRepositoryOfReference: The publication has an author with a given institutional repository of reference

Subscriptions•Repository managers can subscribe to the service to receive notifications
about records “assigned to them” and specify• Topics: enrichment.X or addition.Y• How to be notified: RSS feed, email, APIs, etc.• When to be notified: instantly, every K days• Criteria on record fields (predicate)
•Repository managers can test their subscription by searching the collection of potential notifications
84
Notifications•The service can notify the repositories in different ways
• OpenAIRE recommended repository APIs for metadata ingestion (e.g. SWORD project); software modules for known platforms will be considered (e.g. DSpace, Eprints)
• email to the repository managers• RSS feeds
•The service avoids redundant notifications by keeping a history of delivered notifications
