Greetings,
I'm looking for best practice on how to modularize using xinclude and access image files using imagedata/fileref.
I have a tree of resources, mostly various image files, such as scanned documents.
These are in a rather large tree of folders based upon either a kind of date/time of occurrence or by topic.
These need to be composed to tell a story.Â
The textual content, along with inclusion of images, is placed in docbook xml files that are also scattered around the tree.
Some of the store line is time based and will have dcbkxml interspersed in say the chronological folders.
So a given year story line dcbkxml will be xinclude'ing subfolder dcbkxml files, which have textual components and imagedata stored in current directory or sub*directories.
Other story lines are topical and span across the time line, hence the dcbkxml will be in a Topic/subtopic folder, but needs access to image data spread across the time line folders.
After various attempts, I had settled on simply setting the xml:base to be the root location of the whole tree, with a path from the top of the file-system hierarchy.
The enabled a simple referencing system:
- forÂ
xinclude/hrefÂthe path simply specified the relative location below theÂ
xml:baseÂlocation,
- forÂÂimagedata/filerefÂthe path likewise simply specified the relative location below theÂÂxml:baseÂlocation
It has been suggested that this is a less robust method, and one alternative was to suggest setting aÂ
xml:baseÂusing relative paths.
At the time the method was being considered, the tree was not well defined, and undergoing some changes.
To have used relative paths, e.g.Â
xml:base="../../"Âwould present problems if a part of the tree needed to move.
To do a global change across xml files of a specified relative path from theÂ
xml:baseÂwould be easy.
To do a global change across xml files of a specified relative path in the form of "../../" would be problematic.
The downside of the this whole approach is theÂ
xml:baseÂis in every dcbkxml file, yet it is the same, so easy to change, i.e. global replacement, should the root need to be relocated.
What is the best practice for managing this?
Best regards,
..Otto
