AC Flat Examples

This page contains examples of usage of Audubon Core in tabular form. It is not normative and at this writing contains only proposals.

When using a simple spreadsheet or single tables for data management, it may be necessary to flatten the ac accesspoint structure, i.e. the values of the ac:variant: "Thumbnail", "Trailer", "Lower Quality", "Medium Quality", "Good Quality", "Best Quality", "Offline" are used as prefixes for additional properties in a special acf (Audubon Core Flattened) namespace.

Example 1:

dcterms:identifier

dcterms:title

acf:thumbnailAccessURI

acf:thumbnailFormat

acf:thumbnailImageWidth

acf:thumbnailImageHeight

acf:goodQualityAccessURI

acf:goodQualityFormat

acf:goodQualityImageWidth

acf:goodQualityImageHeight

acf:bestQualityAccessURI

acf:bestQualityFormat

acf:bestQualityImageWidth

acf:bestQualityImageHeight

Example 2:

This unfolds Example 1 and shows the approach illustrated near the bottom of the section Multiplicty/Cardinality in the AC normative page. As there, this is simply an unfolding of the table of Example 1 comes only at the cost of two additional cells per variant, namely the repeated required terms. It also requires a second, single row table that is a proper subtable of the Example 1. It needs no new terminolgy, and if it did, so would all the other cases mentioned in Multiplicty/Cardinality. There is no requirement stated in AC that a tabular representation have only one row, but a question arises as to how best to serve AC users who require such a representation.
