* Markus D: how can we realize the simple thing : time series —> progenitor

need some description of an Activity : Extraction of a mag from an image etc .. follow the Prov relations : wasDerivedFrom or wasGeneratedby + Activity ID+ Used

* Carlos use-case : Provenance from points in a SED or light curve linking points in a data set to other dataproducts : extracted image, extracted spectrum, etc.

Is it simple to solve? * without the prov DM: datalink + progenitor link if it exist datalink + preview if we want to illustrate only the point via an image

* with provenance info select the wasDerived relation in Prov : it will provide you with a progenitor if present.

* François : linking the prov info from Obscore : a prov column which contains a link to a Prov document in one PROV format ( PROV-N, or PROV-JSON)

* IVOA PROV Data model design: A suggestion to handle ActivityDescription by Ole

Example of Ole: musesci_post : a bundle with known roles, with context dependant names , for instance here in the muse:namespace a Bundle class ( W3C compatible) for expressing activityDescription - solves the pb of roles

A realisation of an Activity: uses entities with used roles and generated roles defined in the bundle for description

Musesci_post123 : Activity Instance has relation “Used” with role= “voprov:description” with instance Musesci_post:Bundle

All other used relation should instantiate a role defined in the bundle namespace, here “muse:”

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.
