SSSOM guide for mapping between DwC and MIxS terms

[raissameyer]

Hi @cmungall,

I had a look at the Simple Standard for Sharing Ontology Mappings (SSSOM), which looks like a good option to perform semantically precise mapping of related DwC and MIxS terms (I've had an exemplary first go at this below).

Would you think that SSSOM could be a suitable option for this? Or should I be looking at some other guides?

Best, Raïssa

subject_id	subject_label	subject_category	predicate_id	object_id	object_label	object_category	match_type	comment
dwc:country	Country	DwC Location	skos:closeMatch	MIXS:0000010	geographic location (country and/or sea, region)	MIxS checklist	HumanCurated	DwC term expects the name of a country, while the MIxS term may either be the name of a country or a sea
dwc:decimalLatitude	Decimal Latitude	DwC Location	skos:narrowMatch / ro:concretizes [RO:0000059]	MIXS:0000009	geographic location (latitude and longitude)	MIxS checklist	HumanCurated	DwC term only covers part of the MIxS term (latitude) and specifies the writing convention
dwc:decimalLongitude	Decimal Longitude	DwC Location	skos:narrowMatch / ro:concretizes [RO:0000059]	MIXS:0000009	geographic location (latitude and longitude)	MIxS checklist	HumanCurated	DwC term only covers part of the MIxS term (longitude) and specifies the writing convention

Hey @raissameyer

I am so glad that this is being picked up! I am posted a question about this in GGBN repo since July 2020, but it didn't seem to be picked up. So I appreciate that this is finally being mentioned!

One of the collections of Darwin Core extensions (GGBN) shows some of the similar types of mapping using Simple Knowledge Organization System (SKOS) although it should be noted that SKOS is used to link concepts from different concept schemes.

One of the examples: https://terms.tdwg.org/wiki/mixs:project_name

project name URI: http://gensc.org/ns/mixs/project_name
skos: has related match   http://terms.tdwg.org/wiki/Dwc:datasetName

My knowledge in this is rather limited, but based on what I know, I think it could be a good idea to identify terms that can potentially be mapped using these systems as a guide.

Hi @79-6d,

Much appreciate your input on this and thanks for sharing the example.

Thanks for raising this. Reading more of the documentation of SKOS, especially the part on Mapping and its subsection 10.6.8. on comparing SKOS and OWL terms, I’d agree that it might be worth thinking about using SKOS just to do an initial loose matching of terms of the two standards, but then explore other options for a final more powerful mapping where possible.

@cmungall besides SKOS, SSSOM suggests using OWL or RDFS terms. Are there any additional sources for SSSOM mapping predicatives that we should be looking at?

[raissameyer]

For the DwC-MIxS mapping, we have now used the Simple Standard for Sharing Ontology Mappings, along with (following their guidance) SKOS predicates.
