Import prefixes from CTM #197

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
When importing a TMCL file from CTM, the prefixes are not available in the 
resulting .ono file.

E.g. when importing http://isotopicmaps.org/tmcl/schema.ctm and creating a 
diagram, I expect these prefixes to be defined:
%prefix tmcl http://psi.topicmaps.org/tmcl/
%prefix tmdm http://psi.topicmaps.org/iso13250/model/
%prefix xsd http://www.w3.org/2001/XMLSchema#
%prefix iso http://psi.topicmaps.org/iso13250/

As the CTM importer does not preserve prefixes, these could be loaded from the 
CTM by just opening the file stream and applying some regular expressions.

It would be nice if you add the regExp ;)

BTW A better solution would be a CTMParser which returns the prefixes as result 
of the parsing process.

See http://isotopicmaps.org/ctm/ctm.html#prefix-directive:
[71]    prefix-directive    → '%prefix' identifier reference
[72]    reference   → iri

[5] iri → iri-undelimited | iri-delimited
[6] schema-name → [a-zA-Z]+  [a-zA-Z0-9+-.]*
[7] iri-undelimited → 
schema-name '://'  ([;.)]*  [^#x20#x9#xD#xA;].()]+ ) +  
[8] iri-delimited   → '<'  ([^<>"{}|^`\] '-' [#x00-#x20]) +  '>'

[16]    identifier  → name-start  ('.'* name-part)*
[15]    name-part   → name-start | [0-9] | '-' | '#x00B7' | [#x0300-#x036F] | 
[#x203F-#x2040]

...

Try something like as a start. It's neither clean nor formally correct but it's 
for a convenience method only...
/%prefix\s+(\w+)\s+(\S+)\r?\n
