GOME Level 1B;
L1B
L1C Processor;
Representation Information including all knowledge related to the GOME and
L1B->L1C processor data.
While GOME data and Processor are stored/searched/retrieved on the CASPAR
PDS component, all RepInfo are stored on the Knowledge Manager and browsed
through the Registry.
20.6.2 Scenario ESA2.2 - Data Search and Retrieval
According to the DC Profiles knowledge (see Fig. 20.4 : EO based ontology), dif-
ferent knowledge means different RepInfo modules retrieved during the search and
retrieve session. The scenario is summarized in the following picture.
More in detail, we want to be able to return to an user asking for L1C data not
only the related L1 data plus the processor needed to generate them but also all
the information needed to perform this process depending on the user needs and
knowledge. So different Representation Information are returned to different users
according to their Knowledge Base: after the creation of different profiles (i.e. differ-
ent Knowledge Base) for different users and the ingestion of appropriate Knowledge
Modules (i.e. the competences that you should have to be able to understand the
meaning of data) related to data (based on a specialisation of the ISO 21127:2006
CIDOC-CRM), the Knowledge Manager component is able to understand that an
