Mapping of GSIM referential metadata area for the ESS Standard for Quality Reports Structure (ESQRS) and Information Management Set (GSIM Issue from Sweden)
GSIM class | ESQRS | Information Management Set | Note |
---|---|---|---|
Referential Metadata Subject | Labour force survey | Data Set under processing | |
Referential Metadata Structure | List of metadata as specified in the report, | Structure of referential metadata needed for data set by organisation For example,
| |
Referential Metadata Attribute | Contact, Statistical presentation, etc. | Individual attributes above | Each attribute can have sub-attributes. For example, "Contact" has "Contact organisation", "Contact mail address", etc. |
Referential Metadata Set | Actual populated quality report, e.g., from Belgium | Actual populated metadata set for a specific data set that is under processing | |
Referential Metadata Resource | Collection of quality reports (from the perspective of Eurostat) | Collection of metadata sets for a subject field (e.g., price statistics) | |
Referential Metadata Subject Item | Actual subject (e.g., Belgium's Labour force survey 2021 Q1)? | Actual subject (e.g., data from business register)? | |
Referential Metadata Content Item | Actual content (e.g., email address, quality statements)? | Actual content |
Issues
Issue description | Potential solution |
---|---|
Referential Metadata Subject is currently constrained by Value Domain. Its explanatory text says "GSIM object type may be Product for which there is a list specified in a Value Domain. The Value Domain specifies the list of actual Products for which reference metadata can be reported or authored using this Referential Metadata Structure." but I think creating a list to be able to refer to a subject of referential metadata is too much |
|
Referential Metadata Attribute is currently "defined by" Represented Variable. Although cardinality is 0,1, but its definition "role given to a Represented Variable to supply information in the context of a Referential Metadata Structure" seems to imply that it is not optional |
