Getting started with looking up metadata

  1. 1. Get started: Looking up metadata
  2. 2. funders data clinical trialsgrant #s DOI funders data authors preprint funders grant #s versions preprint funders data clinical trials updates grant #s versions preprint reviews data DOI grant #s versions updates updatesdata data data data data data data citations data data DOI DOI DOI DOI What are you looking for?authors
  3. 3. Citation metadata including… author names, ORCIDs, affiliations, article titles, ISSN, ISBN, pages, issue #, volume #s, dates, DOI
  4. 4. more metadata reference lists, funding data, ORCIDs, license data, clinical trial numbers, errata, retractions, updates and more through our Crossmark service, JATS-formatted abstracts, relationships between items…
  5. 5. What do you want to do? • Look up metadata for a DOI • Match a reference / metadata to a DOI • Look up / retrieve metadata based on defined criteria • Get everything
  6. 6. Have a DOI? Metadata Search (https://search.crossref.org) REST API (https://api.crossref.org) XML API OpenURL
  7. 7. XML metadata records XML API: http://doi.crossref.org/search/doi? pid=youremail@example.org&format=unixsd&doi=10.1162/1526516017 50079104 OpenURL: https://www.crossref.org/openurl? pid=youremail@example.org&format=unixsd&id=doi: 10.1162/152651601750079104&noredirect=true
  8. 8. Match reference to record / DOI Formatted reference? Metadata Search * REST API * Simple Text Query form XML API OpenURL Metadata fragment Metadata Search REST API XML API (need to mark up, minimum metadata requirements) * need to evaluate
  9. 9. Needs evaluation:! - not always exact ! - will return approximate results! - will also return other stuff ! Good for: ! finding approximate results, working with messy data, evaluating matches on your own! Exact:! - field-by-field match! - match or no match at all! Good for: ! auto-populating lists of references!
  10. 10. • Search by title fragment, author name • Find works related to an ORCID • Search by ISSN • Search by grant / award number • Include / exclude terms (using + and !)
  11. 11. Simple Text Query
  12. 12. 3. Retrieve results
  13. 13. REST API • Search, filter, facet, and sample Crossref metadata • No login, no fee • Do whatever you want with the metadata: • Search • Report on funding, publishing, author activities • Ingest scholarly metadata • Locate full text for content mining
  14. 14. What can I ask? • What types of publications is Crossref collecting DOIs for? http://api.crossref.org/works?facet=type- name:*&rows=0
  15. 15. What can I ask? • See how many works have funder information http://api.crossref.org/works?filter=has-funder:true&rows=0
  16. 16. All records for a prefix:
 http://api.crossref.org/prefixes/10.xxxx/works All records with funder information: 
 http://api.crossref.org/prefixes/10.xxxx/works?filter=has-funder-doi:true&rows=0 All records for a prefix with funder information:
 http://api.crossref.org/prefixes/10.xxxx/works?filter=has-funder-doi:true All records with a given funder published in 2017:
 http://api.crossref.org/works?filter=is-update:true,from-pub-date:2017-01-01,funder: 10.13039/100000001,funder:10.13039/100000050 All records with ORCIDs:
 https://api.crossref.org/works?filter=has-orcid:true All records containing a given term: 
 http://api.crossref.org/works?query=quokka REST API (https://api.crossref.org)
  17. 17. XML API • Match references to DOIs • Free (registration required) • Good for reference linking
  18. 18. XML API <query key="CR3" enable-multiple-hits="false" forward-match="true” secondary-query="author-title"> <journal_title>Antiquity</journal_title> <author search-all-authors="true">Anderson</ author> <volume>87</volume> <issue>337</issue> <first_page>879</first_page> <year>2013</year> </query> more info: https://support.crossref.org/hc/en-us/sections/202815006
  19. 19. XML API <query enable-multiple-hits="false" key="key1"> <article_title match="fuzzy">Concluding remarks</ article_title> <author search-all-authors="true">Somiari</ author> </query> Author / title query
  20. 20. XML API <query key="q1" enable-multiple-hits="true"> <unstructured_citation>Hungate, B. A., &amp; Hampton, H. M. (2012). Ecosystem services: Valuing ecosystems for climate. Nature Climate Change, 2(3), 151-152.</unstructured_citation> </query> Unstructured citation
  21. 21. Format Content Type CrossRef DataCite mEDRA RDF XML application/rdf+xml Yes Yes Yes RDF Turtle text/turtle Yes Yes Yes Citeproc JSON application/vnd.citationstyles.csl+json Yes Yes Yes Schema.org in JSON-LD application/vnd.schemaorg.ld+json No Yes No Formatted text citation text/x-bibliography Yes Yes Yes RIS application/x-research-info-systems Yes Yes No BibTeX application/x-bibtex Yes Yes Yes CrossRef Unixref XML application/vnd.crossref.unixref+xml Yes No No DataCite XML application/vnd.datacite.datacite+xml No Yes No ONIX for DOI application/vnd.medra.onixdoi+xml No No Yes Content negotiation (http://citation.crosscite.org/cn) Retrieve metadata records from Crossref, DataCite, and mEDRA
