A common database the ISSN Register

- 1 title on a specific media = 1 ISSN = 1 ldquokey-titlerdquo = 1 bibliographic record

- ISSN Register = 19 million recordsbull 75 000 new records per year

bull Around 30 are for online resources

- Different access solutions subscription-basedbull ISSN Portal

bull Retrieval of the ldquodata filerdquo (=bulk download)

bull Tailored services eg OAI-PMH

ISSN as URIs

- Are ISSN URIs

bull ISSN follow an international standard (ISO 32972007)

bull ISSN are unique within the Register

bull ISSN are persistent (even though they may be suppressed)

- ISSN are not HTTP URI

bull But they link resources anyway

Four rules of linked data Tim Berners-Lee 2006

- Use URIs as names for things

- Use HTTP URIs so that people can look up those names

- When someone looks up a URI provide useful information

using the standards (RDF SPARQL)

- Include links to other URIs so that they can discover more

things

Current achievements

Stepping progressively into the linked data world

ISSN Transitioning to linked data - Cleacutement Oury - IFLA satellite conference Data in libraries - Chicago - August 10th 2016

17

PRESSOO an ontology for continuing resources

- FRBROO object-oriented version of FRBR

- PRESSOO FRBROO for serials and other continuing resourcesbull ldquoAn ontology which aims to represent the underlying semantics of

bibliographic information about continuing resources and more specifically about periodicalsrdquo

- FRBROO chosen as the reference standardbull For its object-oriented approach convenient for linked data

bull More suitable than FRBRER to express the dynamic nature of serials

bull As it allows interoperability with other cultural fields (as a CIDOC-CRM extension)

ISSN Transitioning to linked data - Cleacutement Oury - IFLA satellite conference Data in libraries - Chicago - August 10th 2016

18

Addressing the specific issues of continuing resources

- A specialized data model to represent serials and ongoing

integrating resources

bull ldquofeaturesrdquo (frequency medium)

bull changes that affect them over the time (continuations absorptions

splits)

bull relationships they can have with other serials (linguistic editions)

- Prepared by ISSN IC and the BnF

bull Endorsed by IFLA cataloguing section and intended to become an

IFLA standard

ISSN Transitioning to linked data - Cleacutement Oury - IFLA satellite conference Data in libraries - Chicago - August 10th 2016

19

How to use PRESSOO

- High-level model against which practical rules should be assessedbull Eg examination of PRESSOO by RDA WG on Aggregates

- A ldquotoolboxrdquo a complete set of classes and properties to describe continuing resources

bull Which are derived from the ISSN Manual

bull Suitable for object-centric and event-centric modelling

- A complete ontology to publish a linked datasetbull In conjunction with CIDOC-CRM and FRBROO

bull Using shortcuts sometimes

bull As experimented in ROAD

ISSN Transitioning to linked data - Cleacutement Oury - IFLA satellite conference Data in libraries - Chicago - August 10th 2016

20

ROAD opening access to a subpart of the Register

- Directory of Open Access Scholarly Resourcesbull Developed by ISSN International Centre with UNESCO support

- Free access to bibliographic information pertaining to OA resources worldwide

bull Journal monographic series repositories conference proceedings blogs

- Use ISSN as a matching key with partner databasesbull Abstracting services DOAJ Keepershellip

- A model for a future ISSN Portalo 1 ISSN = 1 webpage = 1 persistent URL

o Semantic information in HTML pages

o Possibility to download ROAD records in PRESSOO ontology

Linked data or linked open data

- LOD policy promote the ISSN as the reference identifier for continuing resources

bull For every person or organization producing publishing or using bibliographic information

bull Offering reliable ways to find the ISSN of a resource

bull Providing ldquoessentialrdquo metadata that allow its precise and reliable identification

- Linked Data policy putting the linking of resources at the center of ISSN strategy

bull More and more links in the Register

bull Use the links to retrieve additional information and enhance our knowledge

bull Publish linked information

ISSN Transitioning to linked data - Cleacutement Oury - IFLA satellite conference Data in libraries - Chicago - August 10th 2016

26

Poor and popular or Rich and lonely

- ISSN ldquolightrdquobull For ldquoessentialrdquo information freely available

bull Maybe based on schemaorg

- ISSN ldquofullrdquobull Based on popular ontologies to promote re-utilisation of ISSN data (eg DC FOAF

schemaorghellip)

bull May require some simplifications and loss of information (notably context information)

- ISSN ldquoexpertrdquobull Based on CIDOC-CRM FRBROO and PRESSOO

bull Full semantic richness of ISSN datahellip

bull hellip but maybe difficult to use by stakeholders not originating from the library world

ISSN Transitioning to linked data - Cleacutement Oury - IFLA satellite conference Data in libraries - Chicago - August 10th 2016

27

On publishing side a new Portal to distribute free

and paid-for content- Completeness of displayed bibliographic information will depend on

bull the consultation context (if free access = only essential information)

bull the type of resource (= free access to records of OA resources)

- Searching facilitiesbull Search facilities provided by the Portal

bull Possibility to access to each record displayed in a dedicated webpage httpissnorg[ISSN]

bull Webpages should be indexed by web search engines

- Download facilitiesbull Individual downloads

bull Machine requests through REST API

bull Envisaged formats RDFXML TTL JSON LD (+ ldquotraditionalrdquo ones MARC21 MARCXMLhellip)

ISSN Transitioning to linked data - Cleacutement Oury - IFLA satellite conference Data in libraries - Chicago - August 10th 2016

28

On production side

- Setting up a ldquodata computing platformrdquobull A tool to ingest store re-compute export bibliographic metadata

bull A RDF triplestore accessible from a SPARQL endpoint

- Enriching Register data with information frombull libraries (eg classifications)

bull publishers

bull ROAD partners

bull any organization publishing in the LOD

- A support for additional servicesbull For librarians publishers or researchers

ISSN Transitioning to linked data - Cleacutement Oury - IFLA satellite conference Data in libraries - Chicago - August 10th 2016

29

As a conclusion- ISSN system and linked data principles amp tools seek similar

objectiveshellipbull Distribution of enhanced and more usable knowledge through the linking of

resources

- hellip following parallel roadsbull Itrsquos time to cross roads

- ISSN Network and ISSN International Centre have already performed experiments in Linked Data and Open Data

bull PRESSOO and ROAD

- We need to go a step further and provide (freely or not)bull More data enriched data

bull Through enhanced tools - to provide better services
