Proposed new Darwin Core environmental terms from ENVO
by John Wieczorek 03 Oct '13

03 Oct '13

Dear all, GBIF has just published "Meeting Report: GBIF hackathon-workshop on Darwin Core and sample data (22-24 May 2013)" at http://www.gbif.org/orc/?doc_id=5424. Now that this document is available for public reference, I would like to formally open the minimum 30-day comment period on the new environmental terms proposed during the workshop and defined in the referenced document. The formal proposal would change the term habitat to align it with the ENVO habitat term. The related issues in the Darwin Core issue tracker is https://code.google.com/p/darwincore/issues/detail?id=178. The Darwin Core term habitat would be redefined as follows: Term Name: habitat Identifier: http://purl.obolibrary.org/obo/ENVO_00002036 Namespace: http://purl.obolibrary.org/obo/ Label: Habitat Definition: A spatial region having environmental qualities which may sustain an organism or a community of organisms. Comment: Examples: "freshwater habitat", "http://purl.obolibrary.org/obo/ENVO_00002037". For discussion see http://code.google.com/p/darwincore/wiki/Event (there will be no further documentation here until the term is ratified) Type of Term: http://www.w3.org/2000/01/rdf-schema#Class Refines: Status: proposed Date Issued: 2008-11-19 Date Modified: 2013-09-25 Has Domain: Has Range: Refines: Version: http://purl.obolibrary.org/obo/ENVO_00002036 Replaces: habitat-2009-04-24 IsReplaceBy: Class: http://rs.tdwg.org/dwc/terms/Event ABCD 2.0.6: not in ABCD (someone please confirm or deny this) The formal proposal would add the following new terms for biome, environmental feature, and environmental material: Term Name: biome Identifier: http://purl.obolibrary.org/obo/ENVO_00000428 Namespace: http://purl.obolibrary.org/obo/ Label: Biome Definition: A major class of ecologically similar communities of plants, animals, and other organisms. Biomes are defined based on factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and other factors like climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation. Comment: Examples: "flooded grassland biome", "http://purl.obolibrary.org/obo/ENVO_01000195". For discussion see http://code.google.com/p/darwincore/wiki/Event (there will be no further documentation here until the term is ratified) Type of Term: http://www.w3.org/2000/01/rdf-schema#Class Refines: Status: proposed Date Issued: 2013-09-25 Date Modified: 2013-09-25 Has Domain: Has Range: Refines: Version: http://purl.obolibrary.org/obo/ENVO_00000428 Replaces: IsReplaceBy: Class: http://rs.tdwg.org/dwc/terms/Event ABCD 2.0.6: not in ABCD (someone please confirm or deny this) Term Name: environmental feature Identifier: http://purl.obolibrary.org/obo/ENVO_00002297 Namespace: http://purl.obolibrary.org/obo/ Label: Environmental Feature Definition: A prominent or distinctive aspect, quality, or characteristic of a biome. Comment: Examples: "meadow", "http://purl.obolibrary.org/obo/ENVO_00000108". For discussion see http://code.google.com/p/darwincore/wiki/Event (there will be no further documentation here until the term is ratified) Type of Term: http://www.w3.org/2000/01/rdf-schema#Class Refines: Status: proposed Date Issued: 2013-09-25 Date Modified: 2013-09-25 Has Domain: Has Range: Refines: Version: http://purl.obolibrary.org/obo/ENVO_00002297 Replaces: IsReplaceBy: Class: http://rs.tdwg.org/dwc/terms/Event ABCD 2.0.6: not in ABCD (someone please confirm or deny this) Term Name: environmental material Identifier: http://purl.obolibrary.org/obo/ENVO_00010483 Namespace: http://purl.obolibrary.org/obo/ Label: Environmental Material Definition: Material in or on which organisms may live. Comment: Examples: "scum", "http://purl.obolibrary.org/obo/ENVO_00003930".

If there are no objections or if consensus can be reached on any amendments put forward, the proposal will go before the Executive Committee for authorization to put these additions into effect after the public commentary period. Cheers, John

Proposed changes to Darwin Core Type term NomenclaturalChecklist
by John Wieczorek 01 Oct '13

01 Oct '13

Dear all, There is a proposal to change the Darwin Core Type vocabulary term dwctype:NomenclaturalChecklist (http://rs.tdwg.org/dwc/terms/type-vocabulary/index.htm#NomenclaturalCheckli…) The basic issue this proposal attempts to solve is that a NomenclaturalChecklist is a data set, not a data record and Darwin Core Type vocabulary is meant to designate the type of a record. The types of records in a nomenclatural checklist data set would be taxonomic names, hence "dwctype:Nomen". As this is a substantive semantic change, we must follow the Darwin Core Namespace Policy's Term Change Policy, section 3.3, Semantic changes in Darwin Core terms, which includes a minimum 30-day public comment period beginning today. The issue is further described on the Darwin Core Project issue tracker at https://code.google.com/p/darwincore/issues/detail?id=177. The proposal would deprecate the current version of dwctype:NomenclaturalChecklist in favor of a new version with the following definition: Term Name: Nomen Identifier: http://rs.tdwg.org/dwc/dwctype/Nomen Namespace: http://rs.tdwg.org/dwc/dwctype/ Label: Nomen Definition: A resource describing a scientific name. Comment: For discussion see http://code.google.com/p/darwincore/wiki/DwCTypeVocabulary (there will be no further documentation here until the term is ratified) Type of Term: http://www.w3.org/2000/01/rdf-schema#Class Status: proposed Date Issued: 2009-01-23 Date Modified: 2013-09-30 Has Domain: Has Range: Refines: Version: Nomen-2013-09-30 Replaces: NomenclaturalChecklist-2009-01-23 IsReplaceBy: Class: ABCD 2.0.6: not in ABCD (someone please confirm or deny this) If there are any objections to the changes proposed for this existing term, or comments about its definition, please respond to this message. If there are no objections or if consensus can be reached on any amendments put forward, the proposal will go before the Executive Committee for authorization to put these additions into effect after the public commentary period. Cheers, John
