Summarize differences between book and outline

I have similar questions. Basically, I want to use the outline module because I need to be able to use nodes instead of only book pages.
Is there an currently an upgrade/transition path from book to outline?
Can someone please also comment on the upgrade path for both the book and outline modules from Drupal 5.0 to Drupal 6.0? Is the outline module going to be part of the Drupal 6.0 core? Is the book module going to be deprecated?
Which module has the better support for web ontology?

If you had just had a look at the issue queue, you would have found that the migration from book to outline is still to be done:

This outline.module will certainly not be part of core. There is a large patch to change the core book.module more or less introducing the same functionality as outline.module , but the fate of the patch is still uncertain at this stage.

What I can say is this:
1) depending on the fate of the book.module patch, I may chose to deprecate this module for D6, in which case I *will* offer an upgrade patch from D5 outline.module to D6 book.module.

2) or else, I will carry on maintaining this module, according to the time I have available.

I am using the module myself on important sites, so you can be sure there will be a long term solution.
See for example: http://minguo.info/election_methods and http://minguo.info/

Is there any update on this? Can you provide a please link to the book.module patch? Thanks

Thanks!

Does outline allow a single node to live in multiple outlines? Will this feature be in D6 book?

@andyschm not yet, but it is planned. I don't think it works in D6 book either but I have to check.

I am currently spending a lot of time to create a second, upgraded D5 release for outline.module, and creating an upgrade path to D6, to use fully the enhanced book.module features, and use D6 outline to add even more functionality to it.

This is a big task and I'm working every day on it. I hope all this will be finalized by the time D6 officially comes out.

Sounds amazing - subscribing

I'm not understanding much of this module. Can I ask some question here?

For example: does Ouline gives the option to give permission to add content to a book only to the user that created that book?
I think that this would be very useful.

I'm using D6 right now, so maybe this function is not included in this version?

@Nithaiah:
The feature you mention is planned but not yet implemented anywhere.

Are you already using the D6 version? It is not yet production worthy, and some data loss might occur by the time the official, stable version is released. If you encounter any bug on the D6 version, please file separate issues for them.

I have now made a precise write up on the differences between book and outline, both for D5 and D6 on the module front page:
