patch for sequencer
Hi,
Here's a patch for the Sequencer.java file which adds a list() and
contains() function. these are just really helpful when i want to generate
my own sequences.

I've been working on something that seems to be similar, so I'm definitely
interested in hearing more about what you've done. I just have concepts
though, so an implementation is more interesting.

thanks.
we're storing the meta data in a seperate 'meta' collection under '/db' much
like the system collection. i hope to make a patch which adds the
requisite changes to enable this functionality.
our links are very similar in concept to auto-linking. in fact, what we've
developed and are working on is a lens service. one property of the lens
service is a linking lens which funcions as auto-linking would. but, there
are other possible lenses, like 'xslt' or 'transform' lens. so this
provides a relatively uniform way to view data thru any single or set of
lens which perform one or more operations on the data. if there is
interest, i'll make a patch for this capability as well.

Ok, I added the patches. I think we'll add a XML-RPC message to carry
forward the sequencer functionality. It might be a little more cumbersome
to use, but will at least keep the functionality.

RE: patch for sequencer
Posted by David Viner <dv...@yahoo-inc.com>.
we're using it over the network.
essentially, we implemented an extended version of xindice (2 or 3 more
patches to come which enable this). in that extended version, we added
several features that are pertinent to our project. They include
auto-creating a Meta object for each Resource (Collection/Document). This
Meta object contains useful metadata about the resource. The Meta object's
xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<meta>
<system type="link" href="/db/test/bar/romeo">
<!--Create time is Mon Jul 15 14:36:02 PDT 2002-->
<attr name="created" value="1026768962473"/>
<!--Modified time is Mon Jul 15 14:36:02 PDT 2002-->
<attr name="modified" value="1026768962473"/>
</system>
<attrs>
<attr name="user-defined" value="stuff" />
</attrs>
<custom>
.. any xml here ..
</custom>
</meta>
Also, we added a feature for "linking" one document to another. Finally, we
allowed users to create new named sequences. This functionality allows us
to use sequences in the same way that a user of Oracle might use Sequence
objects.
These extensions are implemented in a seperate jar file and essentially are
extensions to the core of xindice. I'm still trying to assess how to
incorporate these changes with the recent checkins in preparation for v1.1,
especially in relation to the removal of XMLObjects.

How are you using the sequencer? Since it's an XMLObject I was planning to
remove it. Are you using it over the network or just locally in an
embedded application?
