xPlore development

Julien.Fontaine

Hi guys,

I'm looking for a good tutorial about xPlore development. Do you have any interesting links or white paper ?

I already read the EMC Documentation.

Thanks !

I can give you an example and if you are just generally interested to see what is possible that should fulfill that requirement.

If you read the admin&dev guide and you go to the section that talks about TBO's you will see that for your custom document type you can create a TBO and there is an entry point there you can call. The section also describes things like the structure of the index that is stored and where you may be able to change this.

Depending on your requirement(s) that is likely a good place to start. So to give you an example. I am working with a repository where I store XML documents. Now in the XML world there are all these XSLT to transform and xpath and xquery and..... stuff.

For example if your schema is loose enough that uses can create documents (in XML) and using different structures in the document get a similar result, you may want to when you change the style sheet that produces your HTML, PDF or WORD files know what structures are used and what documents will be affected by your change.

In order to determine what structures, you going to end up using some xpath and xquery functionality.

Great since you now using xPlore and xPlore indexes your content and the index is XML and your content is XML you should just be able to even use the xPlore admin interface and where you have test write your own xquery and you get what you want right? You would think but no, as some folks have seen the XML content may be recognized as XML and treated as such but gets lobbed into a CDATA section which then renders all that nice xQuery useless.

Going back to the start that TBO, you can write something in there and add that XML content of yours into a custom place in the XML index and give you the ability to then go and run that xQuery to your heart's content.

Like with all things custom there is a price to pay.

Having done such a change, the code involved is between 100 and 200 lines if not less and really simple to achieve. I was amazed at how easily and seamlessly the xPlore server just integrates with that change. So for such a change one do not have to touch anything on the xPlore side.
