• Gen2_MI_F3 type FAIR-Maturity-Indicator assertion.
• Gen2_MI_F3 label "FAIR Maturity Indicator Gen2-MI-F3" assertion.
• Gen2_MI_F3 primaryTopic F3 assertion.
• Gen2_MI_F3 procedure "Metadata is harvested by: 1) resolving the GUID (following all redirects) with a Content-Type header specifically searching for some form of structured data. e.g. 'Accept: text/turtle, application/n3, application/rdf+n3, application/turtle, application/x-turtle,text/n3,text/turtle, text/rdf+n3, text/rdf+turtle,application/json+ld, text/xhtml+xml,application/rdf+xml,application/n-triples' 2) resolving any Link 'meta' HTTP Headers (processed independently according to this same process, but not iteratively) 3) parsing the response body either as a hash (for non-linked data) or as a Graph for linked data, or both. 4) All other data is passed to the 'extruct' tool (https://github.com/scrapinghub/extruct) or to the Apache Tika tool (https://tika.apache.org/) for deep exploration 5) Any linked or hash-type data found by those tools are merged with the existing Hash or Graph data To locate the data identifier, hash data is tested for the keys: * codeRepository * mainEntity * primaryTopic * IAO:0000136 (is about) * IAO_0000136 * SIO:000332 (is about) * SIO_000332 * distribution * contains Graph data is tested for the properties: * schema:codeRepository * schema:mainEntity * foaf:primaryTopic * IAO:0000136 (information artifact ontology 'is about') * SIO:000332 (SemanticScience Integrated Ontology 'is about') * schema:distribution * DCAT:distribution (Data Catalogue vocabulary) * ldp:contains (Linked Data Platform) To locate the Metadata's GUID: 1) The values of all Hash keys are compared to the GUID provided to the test (this is not a rigorous test, but the key name cannot be predicted) 2) The Graph metadata is explored for the "objects" of each triple pattern-matching or exact-matching the provided GUID." assertion.
• Gen2_MI_F3 validation "Match found" assertion.
• Gen2_MI_F3 requirements "The Metadata GUID." assertion.
• Gen2_MI_F3 relevance "All" assertion.
• Gen2_MI_F3 rationale "The discovery of digital object should be possible from its metadata. For this to happen, the metadata must explicitly contain the identifier for the digital resource it describes, and this should be present in the form of a qualified reference, indicating some manner of "about" relationship, to distinguish this identifier from the numerous others that will be present in the metadata. In addition, since many digital objects cannot be arbitrarily extended to include references to their metadata, in many cases the only means to discover the metadata related to a digital object will be to search based on the GUID of the digital object itself." assertion.
• Gen2_MI_F3 measuring "Whether the metadata document contains both its own GUID (which may be different from its address), and whether it also explicitly contains the GUID for the data resource it describes." assertion.
• Gen2_MI_F3 examples "" assertion.
• Gen2_MI_F3 comments "A future iteration of this MI will require the use of specific predicates such as schema:identifier to point to the GUID of the Metadata document itself." assertion.
