 check that this can be coded into the VOTABLE serialsition as well.

 apply this template solution to a Pollux activity example, using 2 chained activity templates.

 | **TOPIC: Use of TAP-Autocomplete** |
 | Stelios Voutsinas, Marco Molinaro (16 April, 16:00-17:30) |
-Discussion with Marco Molinaro about the potential use of the TAP-Autocomplete library at Trieste. Topics included a description of the available modes of usage, and what would be required at Trieste for potential installation and use of it. Carlos Rodrigo Blanco also expressed interest, and proposed the idea of having the library as a browser add on, which would work on any TAP GUI.
+Discussion with Marco Molinaro about the potential use of the TAP-Autocomplete library at INAF (Trieste). Topics included a description of the available modes of usage, and what would be required at Trieste for potential installation and use of it. Carlos Rodrigo Blanco also expressed interest, and proposed the idea of having the library as a browser add on, which would work on any TAP GUI.
+Inclusion at INAF would probably work better if the TAP-Autocomplete library is used inside a page that can be served in the same location of the TAP base_url. Since INAF in Trieste is starting using Gregory Mantelet's TAPlib that already sets up that pseudo-frontpage for its TAP instances and also considering that TAP-Autocomplete uses Gregory's adql.js library, then it looks more useful to have the efforts merged.
+Collaboration on this will go on among Stelios, Marco (and Sonia), contacting Gregory and possibly using the votable.js from Andre Schaaff.
+After TAP-autocomplete discussion, with Dave Morris joining in, some discussion took place about the Firethorn application and its potential usage to deploy a global TAP service on top of existing datacollection-limited TAP instances at a data center.
 | **TOPIC: Datalink, SIAV2, SOda feedback** |
 | François Bonnarel (16 April, 17:30-18:30 |
+The Hack-a-Thon discussion about this topic were presented in a talk during the morning session of Day 2: {{open:wp4:multi-d-dal-feedback.pdf}} (François Bonnarel/ Marco Molinaro)
+  * DataLink discovery outside ObsTAP/SIAV2 context : Resource descriptor, ucd, LINK element and Access GROUP discussed
+  * DataLink semantics list extension
+  * DataLink for local resources
+  * Resource Descriptors processing difficulties
+  * SIAV2/SIAV1 services combination
+  * SIAV2 for virtual data missing
+  * SIAV2 request for list of available collections, instruments, facilities
+  * SODA lack of implementations. importance of semantics and description for SODA lines in DataLink.
 | **TOPIC IVOA Time Series/Time Domain** |
 | Dave Morris (17 April, 14:00-15:30 |
+The effort is led by TDIG WG with inputs from DAL, DM. Application is getting in.
+Strong involvment of ASTERICS partners.
+Discovery metadata, TimeFrame details and Time representation reached a consensus
+Data Modeling of TimeSeries is designed as extension of CubeDM. Work by MCD and ML. convergence reachable.
+Serialization and representations: several attempts with several methods (VO-DML and utypes) on the same sample dataset have been tested. VizieR has developed a prototype implementing these various proposals
+Hopefully progresses will be made in VIctoria interop for convergence.
+Discussion in the hack a thon was also focused on how applications (TopCAT, SPLAT, TimeSeries) can ingest that.
+Edimburg group has the intention of developping a TimeSeries specific tool to ingest that and process these data.
-  * Container technology (Docker etc) [BoF]
-  * Publishing tools and auth&aut [Marco]
-  * Informal discussion about DataLink requirements in TOPCAT

+| **TOPIC: Informal discussion about modular, message-driven resource publishing solution** |
+| Marco Molinaro |
+Marco M and Markus D discussed about the reasons to put a modular solution in place, connected risks and potential benefits. Manageability increased costs versus portability and distributed developing effort  were considered.
