[oXygen-sdk] Overwriting or Extending the DITA framework

Thu Feb 7 02:37:32 CST 2013

Hi,

Our final intent is to deliver an MSI that customers of our DITA repository
can install so they can use oXygen xml editor to check ou/check in/View/...
documents from our repository.
The documents are always downloaded to a (configurable) location on the local
hard disk, so no WebDAV support.

-Pascal

Hi Pascal,

What is your final intent?
Do you want to distribute a plugin which can be installed into any Oxygen
installation to allow validation and editing support for your slightly
modified DITA content?

We have some API like:

> ro.sync.exml.workspace.api.util.XMLUtilAccess.addPriorityEntityResolve
> r(EntityResolver)

which would allow you to return your own DTD content when certain DITA public
IDs are resolved. This would work for validating and providing content
completion for your type of documents. But the API does not allow you to see
for which XML content the entity resolver was called because the catalog
resolver is called from many parts of the editor.

Usually this kind of customization is done by distributing a custom framework
(which can be a copy of our DITA framework with some things changed). A
custom framework can also be distributed like an addon together with the
plugin.

We do not (yet) have Java API which would allow you to add an additional CSS
content for rendering a certain opened XML document.
In Oxygen 14.2 (in a couple of weeks) we will add a special type of plugin
extension which will allow you to add a StylesFilter
(ro.sync.ecss.extensions.api.StylesFilter)

You could create your own framework (document type) starting by copying our
DITA document type.
In the Preferences->"Document Type Association" page your document type would
be placed before the usual DITA one (a document type has a priority field
which can be increased). And your document type would have an association
rule which would match only your type of XML documents (you can implement an
interface "ro.sync.ecss.extensions.api.DocumentTypeCustomRuleMatcher" to
create a custom rule matcher).
If you have a custom DITA document type, you can change the CSS and catalogs
in it to suit your situation.

Radu

Hi,

We are creating a plugin for oXygen (14.1)  for our DITA based repository.

All the content is stored in our repository, also the images, ....

When e.g. a topic contains an image element, it only contains the unique
identifier: <image href="GUID-1BA7EFB7-FE54-4643-8AEA-6A2E6A92BD85"
placement="break">

What would be the best way to resolve this. Are there hooks foreseen in
oXygen we  can use? Does oXygen require that this image is on the file system
(in other words does it expect a file path)?

The same for internal links and conrefs.

Kind regards,

Pascal Beutels

Hi Pascal,

Right now how exactly are you opening the XML files from the CMS? Did you
create a custom protocol or are you relying on WebDav?

Oxygen works inside using Java URLs.
Usually references (to images, to links, conrefs) are converted to URLs by
using the URL of the current opened resource (topic). Then Oxygen requests
the content for these URLs to the URL protocol handler.

Most (probably all known) CMS vendors who integrated with Oxygen took this
approach:

> http://www.oxygenxml.com/doc/ug-oxygen/index.html#tasks/howto-cms-plug
> in.html

Basically you use a plugin extension to define a custom URL protocol like:

"sdl://...."

Then you a Browse or "Check out" button on the application's toolbar using a
Workspace Access plugin extension.
The browse button will show the user your custom CMS browser and the user
will choose a resource. Then you call our API
(ro.sync.exml.workspace.api.Workspace.open(URL)) to open the resource using
your custom protocol, something like:

"sdl://path/to/resource.dita"

Oxygen will request content for that resource from your custom protocol
handler and your code will contact the CMS to obtain it. When Oxygen will
find relative resources (like the image
"GUID-1BA7EFB7-FE54-4643-8AEA-6A2E6A92BD85") it will consider them relative
to the opened XML file, will create for them an URL like:

"sdl://path/to/GUID-1BA7EFB7-FE54-4643-8AEA-6A2E6A92BD85"

and will call again your protocol handler to obtain the content for it.

Your custom protocol handler also gets called to produce an output stream if
Oxygen wants to save the content of the edited resource.

In dialogs in which the user needs to browse again the CMS to look for a
certain resource (like Insert Image, Insert Conref, Insert Cross
Reference) we have API which allows you to add a custom action for browsing
the CMS:

> ro.sync.exml.workspace.api.standalone.ReferencesCustomizer.addInputURL
> ChooserCustomizer(InputURLChooserCustomizer)

This API is used in the sample Java class
"CustomWorkspaceAccessPluginExtension" present in our Plugins SDK as a sample
of Workspace Access plugin.

Radu
