REPRESENTING SERIALS METADATA IN INSTITUTIONAL REPOSITORIES

Do we even need journal metadata?

“What we want is articles,” said Gorman, calling the idea of putting them together in things called journals “irrelevant.”

Consider Discoverability

“If you're using repository or journal management software, such as Eprints, DSpace, Digital Commons or OJS, please configure it to export bibliographic data in HTML "<meta>" tags. Google Scholar supports Highwire Press tags (e.g., citation_title), Eprints tags (e.g., eprints.title), BE Press tags (e.g., bepress_citation_title), and PRISM tags (e.g., prism.title). Use Dublin Core tags (e.g., DC.title) as a last resort - they work poorly for journal papers because Dublin Core doesn't have unambiguous fields for journal title, volume, issue, and page numbers.”

Example Article Citation Elements

Chicago Manual of Style Article Title Article Author Journal Title Journal Date Journal Volume Journal Issue Page Range

Journal Article Tag Suite (JATS) <article> <article-meta> <journal-meta> <contrib> <ref-list>

(Peroni, Lapeyre, and Shotton, 2012)

OpenDOAR Directory for IRs

Includes description, policies summary, software platform, OAI-PMH availability, and size

Statistics for repositories includes location, frequent languages, frequent content types, metadata and data re-use policies, and content, submission and preservation policies

About 85% of repositories represented have unknown, unstated, or undefined metadata re-use policies

Metadata Re-use in OpenDOAR

Repository Content Types

Open Access Repository Software

University of Michigan - DSpace

University of Michigan Characteristics

DCTERMS.bibliographicCitation can refer to pre-print or publisher’s PDF

DC.type indicates the genre is article DC.date.issued is year of publication

University of Queensland- Fedora

University of Queensland Characteristics

Include journal title, volume, issue, start page, end page and date, plus ISSN – Highwire Press tags

Sub-type for article not contained in <meta> tags with other Dublin Core elements, but in <body>

Now has Open Access Mandate Compliance field

Columbia University - Fedora

Columbia University Characteristics Includes Publisher and CU DOIs Includes journal title, volume, issue, start

page, end page and date – Highwire Press tags

Uses MODS metadata schema, but not in the <meta> tags

Columbia University MODS Example

eLIS - EPrints

eLIS Characteristics

eprints.type and dc.type to indicate preprint or journal article

eprints tags includes publication title, volume, issue number and date range

Identifier examples include eprints.issn, eprints.id_number, eprints.official_url, and dc.identifier

University of Nebraska Lincoln - Bepress

University of Nebraska Lincoln Characteristics

Uses bepress_citation tags – author, title and date

The citation information for the journal is contained in <body>

PDFs appear to be formatted according to Google Scholar inclusion guidelines

Bielefeld University - LibreCat

Bielefeld University Characteristics Uses Highwire Press tags Includes DOI Includes ISSN RDF example:

UPEI – Islandora

UPEI Characteristics

Highwire Press tags for journal citation, except for citation_lastpage

Additional Dublin Core elements - DC.isPartOf also used for journal title, DC.type for Journal Article, and DC.identifier used for PMID

pre-print status appears in record display

CTU - CONTENTdm

CTU Metadata

DC.Identifier – DOI DC.bibliographicCitation – full citation to

journal article

Starting a Data Dictionary

Identifier – ISSN (ISSN:1612-9768) Identifier – DOI (URI) Relation-IsPartOf – journal title Identifier-BibliographicCitation – full citation Type - “Journal Article” :

http://www.ukoln.ac.uk/repositories/digirep/index/Eprints_Type_Vocabulary_Encoding_Scheme#JournalArticle

Type - “text” : DCMI

Developing Good Practices

Try some tools to practice with Dublin Core metadata -http://www.dublincoregenerator.com/generator.html

Examples of useful documentation for our library include UIC Data Dictionary for CONTENTdm, Best Practices for CONTENTdm and Other OAI-PMH Compliant Repositories

Examples directly related to journal articles can be scattered across many data dictionaries, best practices, and other guidelines

Use Case – Green OA

“About 50% journal articles published during the past 12 months are freely available on the Internet. Nearly half of those OA articles are Green OA. There are millions of them on IRs, traditional journal Web sites, authors’ social network sites, and other Web sites.”

Xiaotian Chen, “Open Access Articles Reaching 50% But Their Retrieval is Lagging,” CARLI Annual Meeting, 2014.

Distinguishing Article Versions MIT metadata indicating publisher’s PDF

Example record: http://hdl.handle.net/1721.1/92550 dc.eprint.version – Final published versiondc.relation.isversionof -http://dx.doi.org/10.1038/srep07467

Use Case – Zotero Integration and IRs

CoinS – recognizes genre as article, but can be missing key citation elements

Embedded Metadata – often detects journal articles as web pages

DOI – can record publisher’s URL, rather than article version present in IR

Retrieve Metadata for PDF – only works if article is indexed in Google Scholar

Use Case – Open URL Link Resolver SFX links to Google Scholar via

getWebSearch, which is a citation title search

Could link resolver link to IRs individually, or, more likely, a collection of IR metadata, such as OpenDOAR?

WorldCat to Google Scholar to IR Link

Final Considerations

Start with the specific use cases for your own institution

Evaluate your policies in light of OpenDOAR policy guidelines

Don’t be afraid to share your metadata and your documentation
