 Screenshot of the Firefox RESTED plugin (steps to retrieve an RDF data source)

Note: Unresolved or pending issues are on top and issues that are done get to the end. To check for RDF in your browser you can (1) use the CETAF Specimen URI Tester (http://herbal.rbge.info) or use a plugin in your browser, e.g. RESTED Client and then adding Header Accept: application/rdf+xml (see example aside)


data.nhm.ac.uk (NHM)

(Work in progress: pending Pending (minor issue does not block)) Requesting “Content-Type: application/rdf+xml” results in 404 (not found) instead of getting RDF (see https://github.com/NaturalHistoryMuseum/ckanext-nhm/issues/458) --Andreas Plank (talk) 14:06, 18 February 2020 (CET)

  • minor issue not relevant because header “Content-Type: application/rdf+xml” is meant for the (returned) resource, not the request --Andreas Plank (talk) 10:40, 20 February 2020 (CET)

id.luomus.fi (LUOMUS)

(Work in progress: pending Pending) The requested RDF does not describe the requested CETAF-ID http://id.luomus.fi/GL.749 itself, the ID “hangs somewhat in the air”:

  1. http://id.luomus.fi/GL.749 gets redirected to http://id.luomus.fi/GL.749?format=RDFXML and
  2. by analysing the RDF via Apache Jena’s rdfparse it reveals that it describes <http://id.luomus.fi/GL.749?format=RDFXML> <http://purl.org/dc/terms/subject> <http://id.luomus.fi/GL.749> just to be related, but
  3. http://id.luomus.fi/GL.749 itself has no related description (rdf:Description) but there are two descriptions http://tun.fi/MY.275076 and http://tun.fi/MY.881682 which do not relate to http://id.luomus.fi/GL.749. So CETAF-ID http://id.luomus.fi/GL.749 “hangs somewhat in the air” because it is not described.

See perhaps the example of CETAF Specimen Preview Profile (CSPP)

specimens.kew.org (RBGK)

(Work in progress: pending Pending) Requested RDF is instead HTML but RDF --Andreas Plank (talk) 14:32, 18 February 2020 (CET)

For instance under Linux: 

wget --header='Accept: application/rdf+xml'  --content-on-error --output-document="specimens.kew.org⁄herbarium⁄K001116483.rdf" "http://specimens.kew.org/herbarium/K001116483"
file specimens.kew.org⁄herbarium⁄K001116483.rdf 
# specimens.kew.org⁄herbarium⁄K001116483.rdf: HTML document, ASCII text, with very long lines, with CRLF, LF line terminators

col.smns-bw.org (SMNS)

(Work in progress: pending Pending) Requested RDF is instead an HTML fragment but RDF.--Andreas Plank (talk) 14:38, 18 February 2020 (CET)

For instance under Linux: 

wget --header='Accept: application/rdf+xml'  --content-on-error --output-document="col.smns-bw.org⁄object⁄S10000227722006.rdf" "http://col.smns-bw.org/object/S10000227722006"
file col.smns-bw.org⁄object⁄S10000227722006.rdf
# col.smns-bw.org⁄object⁄S10000227722006.rdf: HTML document, ISO-8859 text, with very long lines, with CRLF line terminators

herbarium.bgbm.org (BGBM)

( Done) In some RDF files are invalid URI entries i.e. there is a tab/space character in the URI in owl:sameAs and this would break the whole import of data. The error log of triple store loader (tdbloader2) shows something like: 

Bad URI: < http://purl.oclc.org/net/edu.harvard.huh/guid/uuid/a86596ea-6f4d-4b97-bf6f-8d492c0fc8b2> Code: 0/ILLEGAL_CHARACTER in SCHEME: The character violates the grammar rules for URIs/IRIs. ERROR Bad character in IRI (space): <[space]...>

… see for instance in line 63: 

62 <rdf:Description rdf:about="http://www.wikidata.org/entity/Q6382619">
63                     <owl:sameAs rdf:resource="	http://purl.oclc.org/net/edu.harvard.huh/guid/uuid/a86596ea-6f4d-4b97-bf6f-8d492c0fc8b2" />
64                 <owl:sameAs rdf:resource="http://viaf.org/viaf/233473288" />
