WG/DM (MCD/LM)

Status:

VO-DML
- REC document delivered to ivoa repository; new registry records submitted.
"STC" component models (coords, meas, trans)
- wrote xslt translation script for vo-dml/xml to ivoatex
- updated coords model with documentation, extracted from AR versions and STC-1.33 as possible.
  - also changed SpaceReferenceFrame from enumeration to a vocabulary as agreed in Victoria
- process model into ivoatex; incorporate into ivoatex document template
- currently tweaking output formats (table overflows, etc) to make sure all info is included.
- coords WD nearly complete (end of Nov 2018), meas and transform by end of Dec. 2018.
Provenance
- group hit road block in attempt to factor in a new use case... delayed progress of document to RFC
- RFC period started (Oct 22 - Nov 19, 2018)
- Heavy discussion ongoing from review
DatatsetMetadata - no action needed; lien on measurment model
NDCube - no action needed; lien on "STC" component models (meas, trans)
-------------------------------------------------------------------------------------------
TimeSeries
- Face-2-face meeting in Strasbourg, with focus on generating a single model based on cube which covers current use cases
- working serializations of example data products.
SourceDM
- Call to group for people involved in large surveys (GAIA, LSST..) to define which quantities are highest priority

Issues:

VO-DML Mapping: stalement?
- my impression is that the focus group feels they have done what they can with
  - mapping syntax spec; usability demos; helper tools, etc
- but without concrete implementation feedback from external users, they do not have the information needed to work simplifications/changes
- 'alternate' syntax-s are still being worked/proposed which gain attention because the 'appear' simpler, but are not vetted against the requirements.
- TDIG has agreed to consider using serializations using the mapping syntax in their model assessment study, but cannot do so if it produces a road-block to getting the assessment done.

Action Updates:

ACTION-F0518-4: OPEN

WG/GWS (BM/GT)

Status:

Two VOSI errata:
- http://wiki.ivoa.net/twiki/bin/view/IVOA/VOSI-1_1-Errata
1. Only the VOSI Tables XSD version should have been updated to 1.1 (not Capabilities and Availability) -- no impact to implementations
2. The table response examples are using the wrong datatypes--should be vs:TAPType
New Working Draft: Group Membership Service 1.0

Issues:

XML Schema Versioning Note: work out issues with versioning attribute context
UWSRegExt - The note has been completed but its use is in question and will be up for disussion in the joint GWS/DAL/Reg session.

Action Updates:

None
