VOTable 1.4 is a backward-compatible revision whose primary purpose is to support a new TIMESYS element. For more information on TIMESYS, see this note: A Proposal for a TIMESYS Element in VOTable The other main differences between version 1.4 of VOTable and the preceding version 1.3 are:
• Applying erratum VOTable 1.3-1, un-deprecating COOSYS.
Changes made during the Working Draft phase are noted here: VOTable 1.4 Working Draft Notes
Update (2019-06-11): New PR Document uploaded to correct document date and status.
• Applying erratum VOTable 1.3-2, permitting F0 in precision. • Applying erratum VOTable 1.3-3, clarifying the meaning of arraysize="1". FutureThe VOTableInfo page contains a list of proposed changes that, during the WD phase, were agreed to defer to a future version. When the document maintenance is transitioned to GitHub, those item will be converted to GitHub issues.Reference Interoperable Implementations

Comments from TCG member during the RFC/TCG Review Period: 2019-06-05 - 2019-07-19 WG chairs or vice chairs must read the Document, provide comments if any (including on topics not directly linked to the Group matters) or indicate that they have no comment. IG chairs or vice chairs are also encouraged to do the same, althought their inputs are not compulsory. TCG Chair & Vice ChairApplications Working GroupData Access Layer Working GroupDocument looks fine; TIMESYS addition a useful one at current stage. I see a small discrepancy (document heritage driven, I suppose) in asking COOSYS and TIMESYS elements to be placed before the elements that refer to them: COOSYS has this as a SHOULD, TIMESYS as a MUST. I get it cannot be aligned for back compatibility reasons. -- MarcoMolinaro - 2019-07-11Data Model Working GroupGrid & Web Services Working GroupThe document is well written, and addesses the important topic os TIMESYS. No particular comments from me. -- GiulianoTaffoni - 2019-08-12Registry Working GroupApproved from Registry standpoint. I don't have the background to comment deeply on TIMESYS details, but it looks straightforward to implement if needed and the parallel with COOSYS fits nicely. A note on the arraysize=1 clarification: since we're no longer working in the confines of smallest possible text changes for errata, there might be places elsewhere in the text where arraysize is discussed where it would be helpful to mention. Not strictly necessary to address this, just a thought. -- TheresaDower - 2019-06-04Semantics Working GroupWe would like to caution against at this point that the representations of the resources you get when you dereference the vocabulary URL given in the specification will probably change in the course of our work on Vocabularies in the VO 2.0. This does not impact the usability of the present specification where the vocabularies are used as simple word lists. Validators based on the current representations might need (reasonable) adaptations later, though. It's probably ok if this caveat remains here; we don't think this merits mentioning the the spec. Also, we remark that the example in 3.7, where a LINK element is used to reference a SKOS concept, is using an outdated and abandoned vocabulary (on purl.org). Since this is content taken over from a previous version, and a new-style physical quantities vocabulary is not yet finalised, we do not object to leaving things as they are, though. Although it's arguably out of scope for this update, as the responsible WG we're happy to see that VOTable now references VOUnits. Stylistically, we would prefer the text "VOTable documents SHOULD write unit attributes as defined by Units in the VO [3]" so it's clear that validators can issue warnings when they don't. We would also suggest to mention this adoption of VOUnits in the changelog. One important thing, though: VOUnits does not admit the asterics as a multiplication symbol. Thus, "where the symbols . or * indicate a multiplication" must become "where the symbol . indicates a multiplication". (A) Apart from this one point, Semantics is fine with the PR as it stands. Editorial miscellanea: the @version attribute in the schema should be set to 1.4 before uploading the REC; the \ivoatype still says "Working Draft" in the PR and should be turned into "IVOA Recommendation" before upload; also, the status text needs to be fixed (the official wording is in DocStd) before the REC upload.Data Curation & Preservation Interest GroupEducation Interest GroupKnowledge Discovery Interest GroupSolar System Interest GroupTheory Interest GroupTime Domain Interest GroupOperationsLooks good to go from my point of view. -- MarkTaylor - 2019-06-26Standards and Processes CommitteeTCG Vote : 2019-06-05 - 2019-07-19If you have minor comments (typos) on the last version of the document please indicate it in the Comments column of the table and post them in the TCG comments section above with the date.
