Module mkrd

Creation of resource descriptors

The first part of this is an early experiment to automatically create resource descriptors from structured data representations.

While parts of this may be recoverable for smarter gavo start functionality, doing this so that the result is actually useful is hard.

Instead, the new gavo start functionality just fetches one of a few commented RD templates, fills out a thing or two and leaves the rest to the operator.

Classes
	TemplateMacroPackage Macros for RD templates.
	MkrdMacroProcessor a macro expander for RD templates.

Function Details

isIgnoredKeyword(kw)

source code

returns true if kw should not be translated or put into the table.

This is important for all WCS keywords when you want to compute SIAP bboxes; these keywords must not be translated.

structToETree(aStruct)

source code

returns an ElementTree for the copyable content of aStruct.

Note that due to manipulations at parse time and non-copyable content, this will, in general, not reproduce the original XML trees.

getTypeForFTColumn(fitsCol)

source code

returns a DaCHS type for FITS table column.

This currently ignores array sizes and such. Well, people can always fix things manually.
