   * Explore registration of documentation and tutorial notebooks: there is an existing Note about this, which could be endorsed or converted to a proposed recommendation, given takeup
   * pyvo coordination: expand registry search for simplified data discovery options and test backward compatibility of search changes, not just for errors but for general returned results(see https://wiki.ivoa.net/twiki/bin/view/IVOA/IVOANov3RegistryEtherpad)
   * Ongoing validation and curation efforts among registry maintainers, resource curators, and validator and standards authors
   * Explore space-time coverage that was deferred from !VODataService 1.2, approved in 2021A.

On the UCD end of things, we are hoping to have a PEN for version 1.5 of the UCD list ready for TCG review by early 2022. This will include a few statistical concepts, and possibly MOCs, projection and a means to identify oscillation periods from other periodic phenomena; there is also a generic concept for PIDs considered. See https://wiki.ivoa.net/twiki/bin/view/IVOA/UCDList_1-5_RFM for details.

Also regarding UCDs, we will prepare two Errata (to SSAP and SLAP) regarding malformed UCDs used in these standards.

For !SimpleDALRegExt RFC, the vocabulary http://www.ivoa.net/rdf/refframe is under review; we believe it is largely in shape.

This cannot be said for http://www.ivoa.net/rdf/product-type, which is up for adoption by Datalink. We will provide a new prototype based on SKOS before the end of 2021 and evaluate whether it better fits the use cases envisioned.

We have also produced a draft of a vocabulary of object types at http://www.ivoa.net/rdf/object-type. There is no fixed schedule on which this should be evaluated and developed, except that having it for the next revision of obscore would clearly be very useful.

Also, we should revive the process of getting the note on the adoption of the UAT as an IVOA vocabulary endorsed by the TCG.

The objectives from the previous roadmap carry over:
   * <strong style="background-color: transparent;">Priority 1 Objective: </strong><span style="background-color: transparent;">Identifying observation facilities (ground and space). This is a complicated problem requiring integration and maintenance of data from multiple sources. The short-term goal is to produce a "usable product" as soon as possible, even if that is just a massive spreadsheet initially. Ultimately, this needs to be a reference service.</span> 
      * Scope the problem
      * Draft the short-term design
      * Determine contacts for identification authorities
   * <strong>Priority 2 Objective: </strong>Standard List of Coordinate Systems and Reference Frames. 
      * Evaluate the terminology and capabilities from the <a target="_top" href="https://naif.jpl.nasa.gov/">NASA/NAIF SPICE</a> system that can be applied to the IVOA case.
      * Determine timeline to meet implementation with <a href="STC" title="LaurentMichel - 2018-12-19 - 14:41 - r1.7: Space Time Coordinates Documents: Recommendation: Schema: http://www.ivoa.net/xml/STC/stc v1.30.xsd STC v1.30.xsd Errata: STC 1.33 Errata Goal History ...">STC</a>-2.
   * Remaining List of Objectives 
      * Identified the top two priority objectives for immediate action
      * Assess and assign priorities to all remaining objectives
