How to set up oXygen to work with any one NLM/JATS DTD
Raw
00-how-to-set-up-oxygen.md

These instructions assume you already have oXygen installed.

1. Get the DTDs

In your browser, go to one of the following URLs

Then navigate to the download page for the particular version you are interested in. For example, for from this page, click NCBI Book Set, then Version 2.3, then the link for the FTP site, ftp://ftp.ncbi.nih.gov/pub/archive_dtd/books/. From there it should be easy to find the DTD at ftp://ftp.ncbi.nih.gov/pub/archive_dtd/books/2.3/book-dtd-2.3.zip.

Allocate a stable directory on your machine to hold this DTD, download it, and unzip it.

Download that to some local working directory, and unzip it. If you want to plan ahead, we recommend this directory structure

    │   └── 3.0
    └── publishing
        ├── 2.3
        └── 3.0

Be aware that not all of the Zip files on our FTP site are consistent in terms of the directories they create when you unzip them. You might have to do a little cleanup.

For our example, Books 2.3, unzip the dtd files into nlm/books/2.3.

2. Create a clean catalog file

For Books 2.3, copy catalog-v2.xml into a file named catalog.xml. Then, in a text editor, and delete every occurrence of the @xml:base attribute. For example, every occurrence of xml:base="file:///C:/Work/....", no matter what value is given, should be completely removed.

[If you are using Books 2.3, here is an already-cleaned version of the file. To use this, just save it to the same directory as the DTD.]

3. Set oXygen preferences

Note that these instructions haven't been vetted on multiple machines/architectures. They were written against oXygen XML Editor 17.0, on Mac OS X El Capitan. Depending on your platform, there might be significant discrepancies between these instructions and what you see.

Start oXygen, then create a new project and save it. Then got toFrom within oXygen, go to: Options > Preferences, then in the left side-panel > XML > XML catalog. Then click the [ Add ] button, and then navigate to the folder where you have the DTD and catalog, and select the catalog.xml file. Then click "Ok" once to go back to the main preferences dialog box.

Next, if other catalog files already appear in that list, then click the [ Up ] button to put the NLM/JATS catalog(s) at the top.

Before closing this dialog, make sure that:

  • ‘Prefer’ is set to ‘Public’
  • Verbosity is up to you, but we recommend, at least at first, to set it to "All messages", as it can help you trouble shoot OASIS catalog files.
  • Finally, make sure that at the bottom, the "Global Options" radio button is selected.

4. Try it out

If you don't have your own XML file in the NLM or NISO format that you are interested in, check in the output of the DTD's Zip file -- there are usually sample XML files in the target format.

Open up your target XML file, and click the "validate" button (It looks like this)

In the case of the Books 2.3 DTD, in turns out that both sample files are invalid according to the DTD. So if you can fix those problems, until the article validates.

Test also with a known good article.

If that works, then you are all set. Otherwise, take a look in the Errors tab in one of the bottom panes, or the Catalogs tab (you should see the Catalogs tab if you checked "verbose" in the preferences).

Version 2.3 (DAL/BTU) v2.3 (2007-02-02)
Enhancement Release (2.3) following the Working Group meetings
of Oct-Nov/2006-Jan/2007. No backward-incompatible changes.
Archiving loosened even more. New structures for all the DTDs.
Big catalog change = all modules updated to version 2.3
5. Updated public identifiers of the all modules to
February 2007 "v2.3 20070202"
=============================================================
Version 2.2 (DAL/BTU) v2.2 (2006-10-13)

required elements optional.
4. Updated public identifiers of the Book DTD, the Book
Collection DTD, the Historical Book DTD, and book-related
modules (excepting historical book modules) from
"v2.1 20050630" to "v2.2 20061013"
=============================================================

<!-- SCOPE (Suite Version 2.3) -->
<!-- ============================================================== -->
<!-- This catalog is made up of several groups, each with its own
xml:base attribute, for:
- NLM Journal Publishing DTD (Blue)
- NLM Journal Archiving and Interchange DTD (Green)
- NLM Journal Authoring DTD (Pumpkin)
- NLM Book DTD (Purple: includes Book Collection DTD and
Historical Book DTD)
- Archiving and Interchange DTD Suite common (shared) modules
- Suite common (shared) modules from external sources
(table models, general entity sets, etc.) -->
<!-- ============================================================== -->
<!-- CATALOG ORGANIZATION -->
<!-- ============================================================== -->
<!-- GROUPS AND ENTRIES
Entries are grouped into logical clusters, organized by the
particular DTD variant.
Each catalog entry associates a PUBLIC identifier with a SYSTEM
identifier.
The SYSTEM identifier is resolved with respect to the xml:base
attribute which is set on the group element. Thus, for example:
+
uri="journalpublishing.dtd"
=
file:///C:/Work/Tasks/DTDJournal/journalpublishing.dtd
The XML looks like this:
<group >
<public publicId="-//NLM//DTD Journal Publishing DTD v2.3 20070202//EN"
uri="journalpublishing.dtd"/>
...
</group>
-->
<!-- ============================================================== -->
<!-- HOW TO SET UP -->
<!-- ============================================================== -->
<!-- The OASIS catalog and the NCBI Suite of Modules provide a wide
range of flexibility for setting up. Here are two easy ways to
do it:
1. WITHOUT an OASIS catalog (DTD components on a local system):
- unzip the DTD packages you want to use into a single
directory:
- the journal-publishing package
- the archive article package
- the journal-authoring package
- the book package
- create your own DTD customization, if you need to,
anywhere, using local (relative or absolute) SYSTEM
identifiers to reference DTD modules.
- create a document instance anywhere, and point its
SYSTEM identifier to your customized DTD or to the
package DTD you have chosen to use, using a local
(relative or absolute) SYSTEM identifier.
The SYSTEM identifiers used in the DTD modules are relative
to the directory in which you have placed the DTD package
and your customized DTD, and so your editor/processor will
find them when reading the DTD.
2. WITH this OASIS catalog (DTD components on a local system):
- unzip the DTD packages you want to use into a single
directory, or into separate directories.
- in this file (the catalog), edit the xml:base attribute
on the <group> elements.
Here are instructions for the two most likely
configurations:
- if you have unzipped only one of the DTD packages
(journal, archive article, journal-authoring, or
book):
- set the xml:base attribute on the corresponding
<group> element in this catalog to the directory
where you put the unzipped components,
- AND set the xml:base attribute on the last
two groups in this catalog (the modular library
and the public models) to that same directory.
- if you have unzipped more than one DTD package into
a single directory:
- set all xml:base attributes to that directory.
- create your own DTD customization, if you need to,
anywhere, using PUBLIC identifiers to reference the
DTD modules.
- tell your editor/processor about this OASIS catalog
(NB: many apps must be closed and relaunched when
a catalog file is first specified AND when it is changed)
- create a document instance anywhere, and point its
SYSTEM identifier to the DTD you want to use, giving
an absolute or relative SYSTEM path.
Your editor/processor will map the PUBLIC identifiers
in the DTD to the SYSTEM identifiers specified in
this catalog, using xml:base to locate their whereabouts. -->
