Subject: notes and open questions in requirements
We agreed in today’s teleconference that resolution was needed on some of the requirements that included notes and/or open questions. These may or may not require changes to the requirement, but need to be reviewed to make that determination. I have echoed the affected requirements below:
R14 Metadata can have a particular simple typeMetadata columns can have a defined data type. The W3C XML Schema simple types are the default set, but a different datatype library can be specified (through the use of an identifying URI). Facets can be defined to restrict the data type (e.g. length, minimum/maximum, or pattern restrictions). Note: there is an option question around whether it should be possible to define the “type” of complex data (XML fragments) in some sense.
R20 A code list can be derived from existing code lists by removing all common columns before aggregating the remaining columnsIt should also be possible to remove common keys as well as common columns. A column cannot be removed unless all keys that it is part of are removed, and there aggregate must contain at least one key. Note: support for keys as well is columns is not yet implemented.
R21 A derived code list can be required to contain a source code list as a row-wise subsetNote: there is an open question about whether it should be possible to specify that only keys are compared, or that only particular keys are compared.
R22 A derived code list can be required to contain a source code list as a column-wise subsetIt should be possible to specify the subset via keys as well as via columns. Note: support for keys as well is columns is not yet implemented.
R30 Each code list version has a unique identifier, different to the version-independent identifier for the code listThe code list definition contains the version number (or string) as well as the unique identifier (a URI). Note: there is an open question around whether metadata-only code lists should be required to have explicit versions, especially for code lists where it is unlikely that the columns and keys will change over time.
R33 Sets of code list versions can be representedIt must be possible to specify a “configuration” of versions of code lists that together form a coherent set for some purpose. Note: there is open question around whether it should it be possible to include a version-independent reference to a code list, instead of a reference to a particular version of a code list.
This post is intended to prompt discussion (using the list) on these items.
