Files Description
Following is the description of the files used in the different Data Catalog APIs
Structure File
Contains the list of data assets to be loaded into truedat.
group
Group to which the structure belongs. In the case of an Oracle DB it could be the schema, in the case of a Microstrategy report it would be the document, etc. All the structures of the same group must be sent together since when receiving a group it will be inferred that those structures of the same group that are not in the file have been deleted
name
Structure name. Depending on the type of structure, it will be the name of the table, file, report, etc.
external_id
External identifier of the structure. It allows us to identify the structure from the origin of the metadata in order to make successive queries. Additionally, this external identifier is necessary to enable navigation between traceability and catalog.

"field": Asset is a field of another structure. Usually columns in a table
"table": Asset has children with class field.
m:*
It is allowed to enter variable fields to be decided by each connector. These fields can later be used to be displayed in the listings or to order them.
m:data_type_class
ype mapping to be used at points in the application where it is necessary to have a standard data type. For example, this happens to be able to show the quality operators that apply to the structure.
Possible values:
boolean
date
