   * Page 5: 
      * ID: can be of an entity, activity or an agent
      * Default value for DEPTH is one
      * Question: Must ALL keyword be implemented in a service? For instance, could a service set ALL as a redirect to 1? 
         * General opinion here is that implementing ALL is required for the server.
      * Members of a Collection is only tracked if MEMBERS keyword is set to TRUE.
      * In the same way, singuar steps of an ActivityFlow is only tracked if STEPS keyword is set to TRUE.
      * The hierarchical relationships between activities and ActivityFlow as well as entities and Collections are counted in the DEPTH number of relations.
      * AGENT - better keyword or options - 
         * AGENT = EXPLORE, AGENT = ENDPOINT
         * or EXPLORE-AGENT, TRACKAGENT set to TRUE or FALSE
         * leave as it is but open to discussion
      * FORMAT default is set to JSON.
   * Page 4: 
      * The relationship between members of collection or of the activity flow is of hierarcical nature and not to be treated in the same way as a resposibility relation.
   * Page 3: 
      * Suggestion: format can be specified via the HTTP accept header which is common practice for HTTP services wget -d --header="Accept: application/json" {provdal-base-url}?ID=rave:dr4
      * will be discussed further
      * W3C has implementation, has to be checked
      * (W3C) clients communicate for example via json and expect this specific format back
*Prov draft* (refers to rev4224 of [[http://volute.g-vo.org/svn/trunk/projects/dm/provenance/description/ProvenanceDM.pdf][ProvenanceDM.pdf]])
   * Reference implementations are to be put into the wiki - RFC page -<br /> 
      * django.prov_vo, voprov-python, OPUS UWS Server
      * Implementation notes
   * Section 6 - use cases, examples, how to use the model 
      * exists in parts, must be expanded
      * usecases
   * ProvTAP: is it part of the standard or optional? 
      * maybe not mature enough
      * should be part of the standard and
      * ProvTAP needs more explanation, TAP-VOTABLE is not PROV-VOTABLE and has to be mapped
      * how to convert it to VOTABLE
      * Section 6.5 - addition of ProvTAP in the text
   * Section 4.1 - new structure - how to structure the VOTABLE and how to map the data model into the VOTABLE 
      * 4.1.1 - W3C
      * 4.1.2 - VOTABLE
      * 4.1.3 - description serialization
   * Separate document for VOTABLE description? 
      * Will be proposed by Francois and Mireille
   * Entity description will be expanded<br /> 
      * link to the published entity - does it have to be covered in the draft?
      * EntityDescpription is what you know about the entity before the entity is produced.
