<The overview and summary should be written (integrated and distilled) by the topic leader(s), highlighting commonalities and reporting significant variations. It should be refined and agreed by the go-betweens who contributed to this topic. In particular, they should check that critical points have not been missed and that a balance has been attained.>

Regarding the possible items to be managed in catalogues, the RI have shown interest as follow:

• Observation systems and lab equipment: most RI manage equipment which requires management (scheduling, maintenance, monitoring, ...) and some of them are managing or would like to manage this with Information System. Some are already in a standardized approach (OGC/SWE , SSN).
  
  
• Data processing procedures and systems, software: a very few or none mentioned an interest to support this in a catalogue. However, should be done to manage provenance from product datasets to procedures.
  
  
• Observation events: not explicitly mentioned as a requirement most of time. However, should be done to manage provenance from observation results to observation systems.
  
  
• Physical samples: mentioned by a few especially in bio-diversity field.
  
  
• Processing activities: not explicitly mentioned.
  
  
• Data products or results: widely mentioned as being done by existing systems (EBAS, EARLINET, CLOUDNET, CKAN, MAdrigal, DEIMS). Widely standardized (ISO191XX). Copliamce required somethmes with INSPIRE. Once with WIS.
  
  
• Publications: widely mentioned. However very manage the publication on thier own. Links for provenance between publication and datasets is quite common.
  
  
• Persons and organizations: not explicitly mentioned. However this is reference information which is required for the other described items (datasets, observation systems, ...) and for provenance (contact points). 
  
  
• Research objects: mentioned once as feature of interest (airports for IAGOS).

As a consequence, the following strategy to fulfill  ENVRI+ requirements for cataloguing can be proposed. The strategy considers 3 levels of cataloguing.

References catalogues: which are not developed by ENVRI+ or in RI but are pre-existing infrastructures containing reference information to be used. They can be considered as gazetteer, thesaurus or directories... Among them we consider catalogues for:

• persons and organizations,
• publications
• research objects.
  
  

Federated catalogues: catalogue which are pre-existing and partly harmonized in RI but need to be federated  by ENVRI+. Among them we consider:

• data products or results
• results and observation system and lab equipments. It would be interesting to promote the management of metadata on  to improve the provenance.
• physical samples
• data processing procedures, systems and software components metadata management should be promoted to improve the provenance

At last, activity records can be considered, observation events, processing activities, usages logs. They should be provided by RI and harmonized at ENVRIplus level to link together the catalogues and fullfil the provenance requirements. However it is very challenging to achieve this fine grained description. However the tracking of usage of datasets in scientific papers is widely mentioned by RI. This activity record can be used harmonized in ENVRIplus and used as a model of what could used for provenance later on. Then first which dataset most contributed to scientific paper, but later on which dataset is most downloaded, which equipment is most used...
