Cobaltmetrics

Since 2019-03-14

Cobaltmetrics is actively promoting the use the Signposting approach and consumes a variety of link relation types, including cite-as, when extracting URLs from a wide variety of sources (including all Wikimedia projects, hypothes.is, and soon to include CommonCrawl) in order to generate web-scale citation data. Read all about it in the blog post Web-Scale Citation Tracking: Can You Read the Signs? Listen to That Little Voice in Your HEAD Requests.

DataCite Search

Since 2016-11-14

DataCite Search has implemented the following Signposting patterns:
This example shows the Identifier and Bibliographic Metadata patterns implemented for a Landing Page in the DataCite Works Search:

curl -I "https://search.datacite.org/works/10.6084/M9.FIGSHARE.3501629"

HTTP/1.1 200 OK
Content-Type: text/html;charset=utf-8
Link: <http://dx.doi.org/10.6084/M9.FIGSHARE.3501629>
      ; rel=""cite-as"",
      <http://dx.doi.org/10.6084/M9.FIGSHARE.3501629>
      ; rel="describedby"
      ; type="application/vnd.datacite.datacite+xml",
      <http://dx.doi.org/10.6084/M9.FIGSHARE.3501629>
      ; rel="describedby"
      ; type="application/vnd.citationstyles.csl+json",
      <http://dx.doi.org/10.6084/M9.FIGSHARE.3501629>
      ; rel="describedby"
      ; type="application/x-bibtex"

DataCite also implemented the Identifier pattern in the Landing Pages of its Contributor Search, by providing an author's ORCID URI as the target of a link with the identifier relation type:

curl -I "https://search.datacite.org/contributors/0000-0003-1315-5960"

HTTP/1.1 200 OK
Content-Type: text/html;charset=utf-8
Link: <http://orcid.org/0000-0003-1315-5960>
      ; rel="cite-as"

      <http://orcid.org/0000-0003-1291-8524>
      ; rel="author"

This is an example showing the Identifier and the Bibliographic Metadata patterns implemented for a Bibliographic Resource formatted using the RIS citation format:

curl -I "https://doi.pangaea.de/10.1594/PANGAEA.867908?format=citation_ris"

DSpace-CRIS

Since 2017-09-15

Starting with version 5.8.2, the open source DSpace-CRIS system has built-in support for the following Signposting patterns:
This example shows the Author and Publication Boundary patterns implemented for the Landing Page URI, which is identical to the Identifying HTTP URI, of a repository object:

curl -I "http://ktisis.cut.ac.cy/handle/10488/4268"

HTTP/1.1 200 OK
Content-Type: text/html; charset=UTF-8
Content-Length: 30731
Link: <http://orcid.org/0000-0002-9452-3018>
      ; rel="author"
Link: <http://ktisis.cut.ac.cy/bitstream/10488/4268/2/Climate%20Change%20in%20Cyprus.pdf>
      ; rel="item"
      ; type="application/pdf"

This example shows the PDF file that is a constituent resource of the object linking back to the Landing Page URI using the collection relation type of the Publication Boundary pattern.

curl -I "http://ktisis.cut.ac.cy/bitstream/10488/4268/2/Climate%20Change%20in%20Cyprus.pdf"

HTTP/1.1 200 OK

This example shows all these patterns implemented for the Landing Page URI of an object in an Open Journal Systems instance:

curl -I "http://www.annalsofgeophysics.eu/index.php/annals/article/view/7507"

HTTP/1.1 200 OK
Content-Type: text/html; charset=UTF-8
