DwC-MIxS TG third meeting follow-up and next steps
by Raissa Meyer 03 Mar '21

03 Mar '21

Dear all, Thank you all, once again, for the productive meeting. Our next meeting will be on March 16th at 4 pm UTC, following our fortnightly rhythm. The link is available in the previous calendar invite and will be used consistently for all recurring meetings. Below, please find sections with a summary of yesterday’s meeting and next steps. == SUMMARY == For extended meeting notes, please see our running minutes document [1]. We discussed any comments and reactions that came up on review of the first-pass mappings. Major outcomes based on this were: For this TG we will focus on the mapping direction of DWC —> MIxS (Related issues: Issue 12 <https://github.com/tdwg/gbwg/issues/12#issuecomment-788964496> and Issue 28 <https://github.com/tdwg/gbwg/issues/28#issuecomment-784801494>) For mappings that relate two terms which have an associative rather than a hierarchical match, we will use skos:relatedMatch (in such cases skos:broadMatch would be inappropriate as it implies that skos:narrowMatch is the inverse). Our mappings should be exhaustive, so if there are multiple possible mappings (including one-to-many, many-to-many, and many-to-one mappings), we will capture all of them in the SSSOM matrix. (Related issues: Issue 12 <https://github.com/tdwg/gbwg/issues/12#issuecomment-788902485>, Issue 13 <https://github.com/tdwg/gbwg/issues/13#issuecomment-788905133>, and Issue 15 <https://github.com/tdwg/gbwg/issues/15#issuecomment-788779469>) We decided that the choice of mapping predicates will be based on semantics only (i.e. are the fields about the same things in the world), and will not consider syntax recommendations (this is in contrast to what we had decided last week for the ‘elevation’ use case). If we do stick with this, we’ll have to make it very clear in our report and when sharing the mapping in the future. We must further ensure that this is compliant with the specification of SKOS semantic relations <https://www.w3.org/TR/skos-reference/#semantic-relations> and SKOS mapping properties <https://www.w3.org/TR/skos-reference/#mapping>(Related issues: Issue 28 <https://github.com/tdwg/gbwg/issues/28#issue-814813294> and SSSOM#15 <https://github.com/mapping-commons/SSSOM/issues/52>) Bill has kindly generated term lists of all non-MIxS-core-redundant MIxS environmental packages terms (see here <https://github.com/tdwg/gbwg/tree/main/dwc-mixs/notebooks/mixs-package-terms> for the notebooks and files). This sets us up to approach the mapping of MIxS environmental package terms to DwC terms. We anticipate that few will qualify for this mapping, as most MIxS environmental package terms are quite specific. This does, however, suggest that DwC could reuse MIxS IRIs for these terms if it needs to extend in that direction, and if the term is appropriate to their application cases. == NEXT STEPS == In preparation for our next meeting, please review the existing mappings to see if any should be updated in response to the major outcomes of this meeting. Please capture any suggestions on our issue tracker <https://github.com/tdwg/gbwg/issues>. look through any MIxS environmental packages (see tabs in the SSSOM mapping spreadsheet <https://docs.google.com/spreadsheets/d/1k6Xe1OREUVISLjw1XLrtLqWsE7QgvWf7lSI…>) of interest to you or your organisation, and highlight any fields that could be mapped to DwC terms. To avoid duplicating efforts, please capture your activity on our issue tracker <https://github.com/tdwg/gbwg/issues>.

Administration of our GitHub repo
by Tim Robertson 25 Feb '21

25 Feb '21

Hi folks, Raïssa asked that I make you all administrators of the GBWG repository in GitHub so you can e.g. categorise issues. I am happy to do so, but I need your GitHub handles. For anyone who would like to participate in this, please send your GH handle directly to trobertson(a)gbif.org<mailto:trobertson@gbif.org> and I will do this. Please be aware you’ll receive an invitation from GH by email that you need to accept. I can see e.g. Pier has not accepted his. You can probably also accept it here: https://github.com/tdwg/gbwg/settings/access Thanks, Tim

DwC-MIxS TG meeting follow-up and next steps
by Raissa Meyer 23 Feb '21

23 Feb '21

Dear all, Thank you all for the productive meeting. To avoid meeting conflicts with GBWG (e.g. 23rd of March), we suggest shifting our regular meetings by one week. If there are no objections, we would thus have the next meeting one week from today (2021-03-02T16:00Z). I’ll send an updated Zoom invite by Friday. Below, please find sections with a summary of today’s meeting and next steps. ==SUMMARY== For extended meeting notes, please see our running minutes document [1]. John kindly did a complete run-through of the DwC to MIxS core mapping and captured it both in our mapping spreadsheet [2] and issue tracker [3]. In today’s meeting we’ve started to discuss any uncertainties around these mappings: Issue 13 <https://github.com/tdwg/gbwg/issues/13> The definition of depth in MIxS core is “Please refer to the definitions of depth in the environmental packages” which impedes appropriate mapping. We will add an issue about this on the GSC issue tracker to prevent this carrying over to MIxS V6. Issue 14 <https://github.com/tdwg/gbwg/issues/14> MIxS V5 does not offer an ID for altitude. This has been added for MIxS V6. Issue 28 <https://github.com/tdwg/gbwg/issues/28> While most MIxS terms specify a constrained value syntax, many of the mapped DwC terms are supposed to be verbatim. We will have to be mindful of this when choosing the mapping predicates, which may change depending on the direction of the mapping (e.g. see issue 15 <https://github.com/tdwg/gbwg/issues/15>). We will also add a column to the mapping spreadsheet to capture this. Most of the terms in the MIxS environmental packages are either redundant with those in MIxS core, or orthogonal to DwC and thus don’t require additional mapping. Before reviewing this in detail, Bill has kindly offered to generate a release of the MIxS environmental packages containing only the non-redundant terms and link it on our issue tracker. We’ve additionally addressed issue 24 <https://github.com/tdwg/gbwg/issues/25> and issue 25 <https://github.com/tdwg/gbwg/issues/24> which, though not in the immediate scope of this TG, may be of interest. As captured by Bill here <https://github.com/tdwg/gbwg/issues/27>, we have also touched on how one-to-many/many-to-one/many-to-many mappings may proliferate through star-schemas used in DwC implementations. ==NEXT STEPS== In preparation for our next meeting, please review the first-pass mappings and add comments or reactions to the respective issues. PLB and others that are interested are welcome to add comments about the semantic differences between the definitions, which may provide a foundation for a deeper integration following this TG's work. RM will add a ticket on the GSC issue tracker about the MIxS core depth definition. Bill has kindly agreed to generate a MIxS V5 spreadsheet of the only the non-MIxS-core-redundant MIxS environmental package terms, which we will move over to the mapping spreadsheet once ready.

DwC-MIxS TG meeting follow-up and next steps
by Raissa Meyer 11 Feb '21

11 Feb '21

Dear all, Thank you all for the great first meeting! We apologise again for the short notice, and hope to have the complete group together next time. Below, please find sections with a summary of our first meeting, next steps, and a regular meeting poll. ==SUMMARY== For extended meeting notes, please see our running minutes document [1]. We’ve taken the opportunity of this first meeting to start discussing how best to approach building DwC-MIxS interoperability. We’ll first be starting with the mapping of DwC and MIxS terms using the MIxS IRIs (according to Bill currently reserved by not yet live) and the DwC IRIs. This will be followed by the building of an extension with all (or at least most) unmapped terms. For the mapping, we’ll be using the SSSOM matrix [2] which follows the structure of subject (DwC term) predicate (mapping predicate) object (MIxS term). To collaboratively work on the mapping, we’ve set up this mapping spreadsheet [3]. As we fill this out, it’s very important to select an appropriate mapping predicate [4] for machine-level understanding. We should also make liberal use of the comment column to note any concerns or inconsistencies. One-to-many and many-to-one mappings will be captured by duplicating the relevant subject/object in a separate row. Please use our issue tracker [5] to note any comments or difficulties during the mapping, with one issue per term. This will help us transparently log and discuss the challenge as we overcome it. ==NEXT STEPS== John Wieczorek has kindly taken a first pass at the mapping in our spreadsheet and created issues on our issue tracker for discussions/comments. In preparation for our next meeting, please review the first-pass mappings and extend them by mapping any terms that are of particular concern to you in the packages. note any issues/uncertainties (such as duplicated labels on different MIxS terms) on our issue tracker. also, on our issue tracker, note any other challenges/questions in mapping the terms or using the map for implementations. ==REGULAR MEETINGS== To continue the work of the TG we’ll be having regular meetings every two weeks. Please fill out this doodle poll <https://doodle.com/poll/ssy3z9ucrpu9krkk?utm_source=poll&utm_medium=link> to find a suitable weekday. Don’t worry if you can’t make the exact date in the poll this time around, this is more to find a convenient day for all subsequent meetings. According to the output of the previous doodle poll, the time option is limited to 4 pm UTC. Please let us know if this should pose a challenge for any of you. Thank you and best wishes, Raïssa and Pier [1] Running notes document https://docs.google.com/document/d/1569Q7D0Tm03vRQmu2L2WykI63Uk8Aa20GJBC7kU… <https://docs.google.com/document/d/1569Q7D0Tm03vRQmu2L2WykI63Uk8Aa20GJBC7kU…> [2] SSSOM mapping https://github.com/mapping-commons/SSSOM <https://github.com/mapping-commons/SSSOM> [3] DwC-MIxS mapping spreadsheet https://docs.google.com/spreadsheets/d/1k6Xe1OREUVISLjw1XLrtLqWsE7QgvWf7lSI… <https://docs.google.com/spreadsheets/d/1k6Xe1OREUVISLjw1XLrtLqWsE7QgvWf7lSI…> [4] Mapping predicates https://github.com/mapping-commons/SSSOM/blob/master/SSSOM.md#common-mappin… <https://github.com/mapping-commons/SSSOM/blob/master/SSSOM.md#common-mappin…> [5] Issue tracker https://github.com/tdwg/gbwg/issues <https://github.com/tdwg/gbwg/issues> [6] Doodle poll https://doodle.com/poll/ssy3z9ucrpu9krkk?utm_source=poll&utm_medium=link <https://doodle.com/poll/ssy3z9ucrpu9krkk?utm_source=poll&utm_medium=link> — https://orcid.org/0000-0002-2996-719X

Darwin Core to MIxS Core mappings - first pass
by John Wieczorek 09 Feb '21

09 Feb '21

Hi folks, Great meeting to get things started today. I have finished adding mappings from Darwin Core to MIxS Core in the spreadsheet Raïssa shared ( https://docs.google.com/spreadsheets/d/1k6Xe1OREUVISLjw1XLrtLqWsE7QgvWf7lSI…). There are a few subtleties to be aware of, but I think I have captured all of that in the comments. One term, geo_loc_name, currently has two rows to describe it because I added one rather than replace Raïssa's. Hopefully this is a useful start. I did not add issues yet because I do not have sufficient rights to make labels, which I would like to do and add them to the issues as I make them. It would be great if I could be granted that right. Let me know if there are any questions. Cheers, John

First meeting?
by Tim Robertson 15 Jan '21

15 Jan '21

Hi Pier Luigi, Raïssa, all, In December our charter was approved establishing our task group and this open mailing list was created. https://www.tdwg.org/community/gbwg/MIxS/ Would it be a good time to arrange a kick off call to help orient work? I’m happy to help with zoom hosting if desirable. Many thanks, Tim
