   * waiting 
      * DALI-1.2 (has some material)
      * SIAP-2.1
      * SODA-1.0 (feedback)
---+++++ issues
   * SSLDM-2.0: not in VO-DML, is it a problem for SLAP-2.0?
   * CCW-winding polygons: JD summarizing: how to go on after
---+++++ documents
   * Note: TimeSeries Discovery and Access DAL procedure [22.07.2018] - as per roadmap
   * Note: Recent DAL protocols feedback [22.07.2018] - as per roadmap
   * (iWD): SLAP-2.0
   * (iWD): SSLDM-2.0

---+++ 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
      1 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
