REPRESENTING SERIALS METADATA IN INSTITUTIONAL REPOSITORIES
Lisa Gonzalez, Electronic Resources Librarian
NASIG 2015Washington, DC
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:
<link rel="DC.relation" href="urn:ISSN:0361-073x" />
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
