Re: [jats-list] how to identify a XML file as JATS

["Imsieke, Gerrit, le-tex" <gerrit.imsieke@xxxxxxxxx>]

Hi Matteo,

if youbre using emacs nxml mode, you need to convert the .rng files to 
.rnc (Relax NG compact syntax). You may use 
https://github.com/oleg-pavliv/emacs/tree/master/xsl/RngToRnc-1_4 to 
convert it. Or I can send you the converted files b I just tested 
whether it works on the JATS .rng files.

Then you have to set up schema association rules for nxml.

You can put a file schemas.xml in your working directory, like this:
<locatingRules xmlns="http://thaiopensource.com/ns/locating-rules/1.0";>
  <uri pattern="*.jats.xml" 
uri="file:/home/gerrit/XML/JATS/schema/JATS_Archiving_1.0/rnc/JATS-archivearticle1.rnc"/>
</locatingRules>

It should be possible to store these rules centrally for emacs, but they 
are somewhat limited in the criteria upon which you can make nxml select 
a certain schema. 
http://infohost.nmt.edu/tcc/help/pubs/nxml/schema-locating.html

Otherwise, you may use the xml-model processing instruction after the 
XML declaration in order to associate a Relax NG schema with the XML 
file, like this:

<?xml-model 
href="file:/c:/cygwin/home/gerrit/XML/JATS/schema/JATS_Archiving_1.0/rng/JATS-archivearticle1.rng" 
type="application/xml" schematypens="http://relaxng.org/ns/structure/1.0";?>

But few applications honor this PI. oXygen XML editor is a notable 
exception.

You donbt have to include a schema declaration at all in the file. You 
just invoke jing with the schema and the file location.

If the DOCTYPE declaration is present, most XML parsers will look for 
the DTD in order to resolve named entity references. You may not supply 
a schema of another type than DTD in the DOCTYPE declaration. But you 
may well drop the DOCTYPE declaration altogether.

If you use xlink:href attributes in the document, you may need to 
declare xmlns:xlink="http://www.w3.org/1999/xlink"; in your document 
which didnbt seem to be necessary with the DTD (to my surprise).

Hope this helps.

Gerrit
