I’m talking about the home page of blogs, not the Categories home page.
Here’s the use case:
* I Have blog1 using categoriesA
* I have blog2 using categoriesA
* When I go to blog1.WebHome I want to see only blog posts from blog1
* When I go to blog2.WeBhome I want to see only blog posts from blog2 On 14 Mar 2017, at 10:55, Denis Gervalle

Hi Edy, Vincent,
Based on your concerns and our findings, I have finally crafts a design document here:
http://design.xwiki.org/xwiki/bin/view/Proposal/BlogImprovemultiblogsupport
You were right Edy about the need to better support existing sharing of categories and we
have therefore improve our proposal in that regard. It now covers mostly all features of
the existing blogs like before, with one small difference: the uncategorised posts from
other blog spaces than the Blog space will not be displayed outside of that local blog
space.
After further thought, we noticed that the actual Blog space will be slightly special
because it will stay the only blog space to store both blog post and blog categories in
the same space. Which has the consequences of having the Categories WebHome and the blog
WebHome at the same location. The general intend is to properly slip set of categories and
blogs, so that the home of a set of categories display posts from all blog posts using any
of the categories of the set, while the home of the blog will display only post of that
given blog. For the special Blog.WebHome we have finally decided to do a mix, which is all
blog posts using any of the categories in Blog + all posts in Blogs. This is the closest
to the actual behaviour and the best compromise in our opinion to move forward. Regarding
the categories themselves, these will continue to work as before, and display all blog
posts of that particular categories, whatever the blog there are from is.
All that said, in this first version, we will not support the creation of new blogs that
share a set of categories from the UI. All new blogs will be created with its own set of
categories stored in a subspace of the blog space names Categories.
I hope the linked design document will respond to all your remaining questions. Don’t
hesitate to ask if you still have concerns about the proposed change.
Thanks for this design page and the precision it brings.
FYI I’ve added some questions/comments in annotations on that document.
My main question is how do you configure a new blog to display all blog posts using the
same categories that it’s using, i.e. to make it behave similarly to the Blog.WebHome
blog? I was thinking that this could be done without UI and by introducing an “aggregate”
boolean xproperty in the BlogClass (it would be “false” by default). Currently the only reason why Blog.WebHome got
that special feature is because it is mixed with the WebHome of the Blog space categories.
In a normal situation, the WebHome of the category space will display the aggregation
except for uncategorised post. Do you really feel there is a great value to have
uncategorised post of a given blog aggregated with posts that use the same categories as
that blog ? My feeling is that it looks complex and not easy understandable.
I was not referring only to uncategorised posts. I was talking about a blog listing all
blog posts (even if they come from other blogs) sharing the same categories. Basically the
blog aggregation use case.
So, for categorised posts, you will get them aggregated in the categories themselves like
it is already the case now. And we will keep the “All” link that will point to the WebHome
of the space holding the categories and that will display all posts sharing that set of
categories. What we are unable to do is finding uncategorised post from blogs that are
using that set of categories to list them as well. And the why is related to the lazy link
between the post and its blog, see my comments on the design page. This last two cases are what we propose for now. * I
create blog3 that uses categoriesA but when I go to blog3.WebHome I want to see all blog
posts from all blogs using categoriesA (even uncategorised ones), i.e. all blog posts from
blog1, blog2 and blog3 (if any).
This last case (apart from the uncategorised ones) is precisely what the categories space
WebHome will be, and accessible through the “All” link in the category panel of all three
blogs. And the way all blog lists are managed will be through the same BlogPostList macro
that will be therefore usable by the end user in a different context if need be.
Displaying them including the uncategorised posts of all three blog is much harder to
achieve as I have explained, since there is currently no direct link between the posts and
their blog. So, I see this as an advanced use case, that would need much more work. Is it
a blocker for you ?
It’s both a question of backward compatibility and new use case for me.
Here’s what I’m proposing to be precise:
* Introduce a new “aggregate” xproperty in BlogClass
* When this property is set the blog displays not only the posts from its own space but
also all posts from all other blog posts using the same category set
* Set this property for the main blog so that it behaves exactly as it does now before the
change
* This will also allows to create new blogs that are aggregating, i.e. it’ll be possible
to have more than 1 aggregating blog in the wiki.
Thanks
-Vincent
