HAMR: Human/Authority Metadata Reconciliation

HAMR: Human/Authority Metadata Reconciliation

Sean Chen, Tim Donohue, Joshua Gomez, Ranti Junus, Ryan Scherle

A tool for a curator to determine whether the various fields of a metadata record are correct. Takes a metadata record, locates any identifiers (e.g., DOI, PMID). Retrieves a copy of the metadata record from an authoritative source (e.g., CrossRef, PubMed). Displays a human-readable page that compares fields in the initial record with fields in the authoritative record. Each field is color-coded based on how well it matches, so the curator can quickly identify discrepancies.

Focus:

• Dublin core (maybe qualified)
• framework that allows multiple authority sources
• NOT focusing on author names (ORCID is already working on this), except the fact that they are strings, and we'll do basic string matching

Possible authority sources:

• pubmed
  • Sample pubmed query (in Java): DSpace PubMedPrefillStep.java (From Populate Metadata from PubMed)
    • See 'retrievePubmedXML()' in above java code for actual call to PubMed
    • Mapping happens here: See pmid-to-dim.xsl for a sample XSLT crosswalk to translate PubMed format to a qualified dublin core (internal DSpace metadata format)
  • More examples of querying PubMed: http://www.my-whiteboard.com/how-to-automate-pubmed-search-using-perl-php-or-java/
• crossref
  • simply send the DOI to crossref, and get JSON/XML back

    • http://api.labs.crossref.org/10.2307/1935157.xml
    • java code that includes a lookup
  • Metadata Search -- send a text query, receive a list of matching records
• google scholar - does it have an API?
• mendeley - Mendeley API
• vivo
• bibapp
