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 and/or Content-Type: application/rdf+xml (see example aside)

data.nhm.ac.uk (NHM)

( Pending) 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)

specimens.kew.org (RBGK)

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

For instance under Linux:

wget --header='Accept: application/rdf+xml'  --header='Content-Type: application/rdf+xml' --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)

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

For instance under Linux:

wget --header='Accept: application/rdf+xml'  --header='Content-Type: application/rdf+xml' --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" />
65           </rdf:Description>
