A Relationship describes the relationship 43 between two Topics.
Relationships:
� A Relationship relates a Topic.
Example: A ‘Person’ Entity may be represented in one Data Asset in a
‘Customer’ context because it is part of a CUSTOMER_INFO table.
However, the same Entity may be represented in a ‘Suspect’ context on a
law enforcement website. The metadata that is associated with the
‘Person’ Entity would be different in each context e.g., the ‘Suspect’
context would likely include physical characteristic metadata (height, hair
colour, etc.), while the ‘Customer’ context would not.
A Data Asset is a managed container for data. In many cases, this will be
a relational database; however, a Data Asset may also be a website, a
document repository, a directory or data service.
Relationships:
� A Data Asset provides management context for a Digital Data
Resource.
Example: A document that is stored and managed within a Data Asset
(such as a document repository) has management context provided for it
through the metadata that is associated with that document within the
document repository. Such metadata may include the AGLS Metadata
Standard attributes that are described in the Data Description section.
A Data Steward is a person responsible for managing a Data Asset.
Relationships:
� A Data Asset may be managed by a Data Steward.
This concept represents the four other AGA reference models: the
Business Reference Model (BRM), the Service Reference Model (SRM),
the Technical Reference Model (TRM) and the Performance Reference
Model (PRM). Its purpose is to provide a linkage to these other reference
models, which are themselves Taxonomies. These are depicted as a
special kind of Taxonomy due to their importance in the overall
classification of information.
Relationships:
� The other AGA Reference Models are types of Taxonomies.
43 It should be noted that the term ‘relationship’ is used in two ways here. The concept named ‘Relationship’ participates in
relationships with other concepts in the abstract model and also defines the relationship between topics when it is applied to a
specific scenario.
