Study Notes

Aggregations and Content Management

An aggregation of News Release objects from 2015 can be filtered to exclude those containing the phrase "AFRICON 2015" and include those with the word "Africa" from any category, or written by authors from Africa.

Supplemental Indexing

Externalizing memory through indexing data can reduce query times in databases.
Indexing provides an alternative method of finding specific data in a larger repository.
Supplemental indexes can assist in esoteric searching, such as creating a list of IDs of content objects matching specific criteria.

Aggregations as Content Objects

Aggregations can be treated as content objects with attributes like title, introduction, date created, and date reviewed.
This approach allows for inherent features like permissions, workflow, versioning, and URL addressability.
Aggregations can be "carried" on the backs of content objects with referential attributes that allow multiple references.

Content Relations and Aggregations

The line between content objects and content aggregations blurs when modeling content relationally.
Aggregations can be considered content in themselves, fulfilling the two tests of content: created by editorial process and intended for human consumption.

Aggregation Composition and Limitations

Aggregation composition is content in itself, requiring specific orders and curation.
Quantity limitations can be applied to aggregations, such as requiring a minimum or maximum number of content objects.

Permissions and Publication Status Filters

Aggregations should be dynamically filtered for both the current visitor and the publication status of the content.
This means an aggregation might show different content for different visitors or under certain conditions, and some visitors might not see any content at all.
