  Central Secretariat for

  International Standards and

  Technical Reports

  Dr. Yushi Komachi

the Project Editor started his works for revising ISO/IEC TR 9573-11. He visited ISO Central Office (ISO-CO) and identified that ISO-CO had a revised DTD (SGML-DTD ver.0.94) for publishing International Standards and Technical Reports.

Recognizing that ISO-CO requires XML-DTD corresponding to the SGML-DTD ver.0.94, he and his colleague developed an XML-DTD.

2. XML-DTD

2.1 Original SGML-DTD and its XMLization

The XML-DTD was developed being based on the SGML-DTD version 0.94.

Major modifications for XMLization are:

1. Comments within declaration are extracted to be separate comment statements.
2. Characters are adjusted according to the XML rule of case sensitivity.
3. All tags are described without omission.
4. Each element is defined separately.
5. All the attribute values are quoted.
6. Attribute types NAME, NUMBER, and NUTOKEN are changed into NMTOKEN.
7. The location of #PCDATA is changed into a head of declaration.
8. Content models are modified without & separators.
9. Characters defined by SDATA are changed into simple strings.
10. Elements declarations are changed without exceptions.
11. URIs are specified to the public identifies.

2.2 Modularization

The XML-DTD was modularized for a more feasible DTD exchange. The modularization was carried out considering the logical structure of the original SGML-DTD (see Figure 1).

All the XML-DTD module files are zipped and attached as attach1.zip. They are shown bellow, where a file with the extension ".dtd" is a driver or a DTD module translated from the corresponding original SGML-DTD file and a file with ".mod" is a new DTD file developed for the modularized XML-DTD representation.

NOTE The values of gtext attributes are generated by a particular processor. Those attributes generation and rendering can be done, for example, by an XSL processor.

2.3 Samples of XML document instances

Three samples of XML document instances are attached as a zipped file, attach2.zip, where the two document instance files:

test1.xml
term1.xml

are sample XML documents translated from test1.sgml and term1.sgml respectively. The test1.sgml and term1.sgml are included in the set of original SGML-DTD files.

Another sample in the attach2.zip is an XMLized International Standard ISO 15178.

3. XSLT translation into HTML

For easy rendering of XMLized ISO standards, the Project Editor tried to translate the XML documents into HTML documents by using XSLT.

The attach3.zip includes an XSLT specification for the translation.

The attach4.zip includes the two two HTML document instance files:

test1.html
term1.html

translated from the two XML document instance files:

test1.xml
term1.xml

respectively, in accordance with the XSLT specification.
