Re: [xwiki-devs] [Proposal] Add a new type of blog (Isolated blog)

So for existing blogs, those that are currently all sharing the Blog space categories, each blog will now only display the blog post of its own space, both in the blog list of their respective WebHome (or Blog page), and for the counter into the categories panel. The only thing that will stay “shared” is the management of those categories. This is just a back compatibility feature, since the idea is no more to share categories between blogs. All new blogs will have their category_location property set to their own Categories subspace.

If we want to reintroduce some sort of aggregating blog, the way it could only work will be with blogs having the same value in their category_location property, but we have no plan about that yet. I hope this makes it clearer. Let me know if you have further questions. -- Denis Gervalle SOFTEC sa - CEO On Thu, Mar 9, 2017 at 14:58, Eduard Moraru &lt;enygma2002(a)gmail.com&gt; wrote: Hi, It may be worth to clarify a bit the behavior and visibility of actual blog posts, now that we have covered Categories and the way to share them between 2 blogs. If "Global.Categories" is used by both the "Global" and the "AnotherBlog" in their configuration (as categoriesLocation), which one of them displays what? It`s not clear to me which one is the global (i.e.aggregator) and which one is the local (i.e. just reusing the other's categories, but not aggregating the other's posts as well) blog in this case. AFAICS right now, they would both display the same content, since, AFAIU, a blog will be displaying all the posts for its configured categories. However, maybe I`ve understood it the other way around. Is it instead the fact that the aggregator would specify a multi-valued categoryLocations with the categories of the blogs it wants to aggregate, while a local blog would only use his own, local categories to display posts? That might work, *however*, it would only be feasible if the aggregating (global) blog was in *read-only* mode. If it`s not read-only and it starts creating posts using one of the aggregated blog's categories, then the new post will start showing in the aggregated (local) blog as well.
