[ckan4rdm] catalogue of CKAN research data repositories

[John Erickson]

Semantic markup following http://schema.org/DataCatalog and
http://schema.org/Dataset can be very useful outside the context of
the big search engines, and esp. can be very useful in supporting
"human curated search."

Specific example: members of the Web Science Trust network of labs
<http://webscience.org/> are developing a Web Observatories vocabulary
<http://tw.rpi.edu/web/WOschema>, following the schema.org framework.
The WebObs vocabulary might never become an official extension, but
WSTnet members are already using it as the basis for a crawler that
can extract metadata from known sites, aggregating a
searchable/browsable graph of WebObs sites, projects, datasets, tools,
etc. The WebObs vocab inherits Dataset and DataCatalog (and other
schema.org) classes, so those remain indexable by the schema.org
partners even if the WebObs terms aren't included.

If someone were to use the vocabulary in a malicious way, a curator
would remove the target URL for teh offending candidate site from the
crawl list. Meanwhile, the markup on the good sites is useful to
curators...
