Maintaining Attributes in Users Namespace

[Bug Importer]

Greetings

Described simply, I would like to maintain the attributes
of a shape that exist in a namespace other
than "SVG","inkscape" or "sodipodi".

That is, I would like to define my own metadata for a
particular shape and be able to maintain it within
theinkscape gui.

An initial proposal for a solution (probably illconceived)
would be to implement the
element "inkscape:userattributes" that would be
subordinate to a <g>. This element would have
attributes whose names were not validated, but simply
displayed in a name-value-pair table-control dialog box
that could by diplayed from the context menu for the
selected shapes in the group. The value column would
be editable.

Using the XML editor would, I suspect, be a little
unfriendly to the expected user community

Is the Extension/Plugin mechanism meant to handle this.
If so, does a detailed description of this mechanism exist.

As a temporary solution, the XML editor already works,
either with inkscape:userattributes="foo=bar;baz=qux"
attributes, or with rta:foo="bar" rta:baz="qux" attributes
(though the latter would require that the outermost <svg>
element include an attribute
xmlns:rta="http://rta.nsw.gov.au/something.dtd"; that URL
doesn't need to exist, it's just a string identifier).

Alan Horkan sent mail (to inkscape-devel and Endre Nagy;

One possible implementation of the idea would be something
like say roundhole or dropshadow in the share/extensions
directory. Note that this extensions functionality won't be
in 0.40, but might be in CVS relatively soon after 0.40.
Inkscape would provide a menu of such extensions; selecting
one would invoke an external program that could allow
editing the attribute values and feeding inkscape with the
updated SVG.

Ted is the person to hassle^Wspeak to on jabber
(http://www.inkscape.org/discussion.php) if you're
interested in this approach.
