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 or on command line:

1. you can use https://www.w3.org/RDF/Validator/ in general
   or use command line tools from Apache Jena (see Documentation), e.g. on Linux:
   /path/to/your/apache-jena-3.15.0/bin/rdfxml --validate "Testfile.rdf"
   # or with log file
   /path/to/your/apache-jena-3.15.0/bin/rdfparse -R "Testfile.rdf" > "Testfile.rdf.ttl" 2> "Testfile.rdf.log"
2. you can more specifically use the CETAF Specimen URI Tester (http://herbal.rbge.info)
3. you can use a plugin in your browser, to basically evaluate redirection to the source RDF, e.g. RESTED Client and then adding Header Accept: application/rdf+xml (see example aside)

data.biodiversitydata.nl (Naturalis)

Pending In some RDF files are invalid URI entries that is, they are not URL-encoded, e.g. <rdf:Description rdf:about="http://data.biodiversitydata.nl/naturalis/specimen/L 0934036`"> having bare spaces or accent characters; URIs having spaces there are many (about ≈278.900), having accent characters there are a view, e.g. with error messages like:

[line: …, col: 68] Illegal character in IRI (codepoint 0x60, '`'): <http://data.biodiversitydata.nl/naturalis/specimen/L%20%200934036[`]...>
[line: …, col: 80] Illegal character in IRI (codepoint 0x60, '`'): <http://data.biodiversitydata.nl/naturalis/specimen/L%20%200799429%20%20%20%20[`]...>
[line: …, col: 68] Illegal character in IRI (codepoint 0x60, '`'): <http://data.biodiversitydata.nl/naturalis/specimen/L%20%200979378[`]...>
[line: …, col: 63] Illegal character in IRI (codepoint 0x60, '`'): <http://data.biodiversitydata.nl/naturalis/specimen/L.4305564[`]...>

These URI entries have to be fixed otherwise it would not be imported, find and replace is fixing this issue manually for the import. --Andreas Plank (talk) 12:30, 8 July 2020 (CEST)

coldb.mnhn.fr (MNHN)

Unicode/XML issues:

Notes for a general work around during harvest/import:

• invalid unicode characters break rdfparse and subsequent import, so the harvested RDF must be fixed first manually at this point --Andreas Plank (talk) 12:33, 8 June 2020 (CEST)
• characters that can not be guessed properly will be replaced by a question mark “?” at that position where the wrong unicode character was before

data.rbge.org.uk (RBGE)

( Pending) the RDF embedded XML contains pure “&” which is not properly escaped in the XML realm (the propper escape is &). Many RDF files e.g. http://data.rbge.org.uk/herb/E00011206, seems a generic problem --Andreas Plank (talk) 16:33, 16 March 2020 (CET)

• it will be fixed during harvesting routine, but provided XML should be valid including escaped ampersand & --Andreas Plank (talk) 16:33, 16 March 2020 (CET)

data.nhm.ac.uk (NHM)

( 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)

No or mixed up RDF description of CETAF-ID

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

id.luomus.fi (LUOMUS)

( 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” (from a descriptive point of view):

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.

--Andreas Plank (talk) 12:10, 20 February 2020 (CET)

id.zfmk.de (ZFMK)

( Pending) The requested RDF does not describe the requested CETAF-ID http://id.zfmk.de/collection_ZFMK/1650/733377/90217 itself, the ID “hangs somewhat in the air” (from a descriptive point of view):

1. http://id.zfmk.de/collection_ZFMK/1650/733377/90217 gets redirected to https://id.zfmk.de/collection_ZFMK/rdf/xml/CollectionSpecimen/1650/733377/90217/?shorturl=1 and
2. by analysing the RDF via Apache Jena’s rdfparse it reveals that it describes something other: https://id.zfmk.de/collection_ZFMK/1650, but unrelated to the ID
3. http://id.zfmk.de/collection_ZFMK/1650/733377/90217 itself has no related description (rdf:Description) and “hangs somewhat in the air”
4. checking the website states a stable URL https://id.zfmk.de/collection_ZFMK/page/CollectionSpecimen/1650 but this very URL does not return any RDF

--Andreas Plank (talk) 12:29, 20 February 2020 (CET)

purl.org/nhmuio (NHMUO)

( Pending) The requested RDF does not describe the requested CETAF-ID http://purl.org/nhmuio/id/41d9cbb4-4590-4265-8079-ca44d46d27c3 itself, the ID “hangs somewhat in the air” (from a descriptive point of view):

1. http://purl.org/nhmuio/id/41d9cbb4-4590-4265-8079-ca44d46d27c3 gets redirected to https://data.gbif.no/resolver/O:L:14 and
2. by analysing the RDF via Apache Jena’s rdfparse it reveals that it describes something other: http://purl.org/gbifnorway/id/O:L:14, but unrelated to the ID
3. http://purl.org/nhmuio/id/41d9cbb4-4590-4265-8079-ca44d46d27c3 itself has no related description (rdf:Description) and “hangs somewhat in the air”

No RDF but HTML

col.smns-bw.org (SMNS)

( 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

specimens.kew.org (RBGK)

( 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

Fixed Issues

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">
