[xwiki-devs] [VOTE] Summary: NS, ND, Parent/Child

Hi devs, So after discussing the topic of Nested in several mails, we need to reach a conclusion in order to start implementing. There are several open questions that I will summarize. Please cast your votes in order to advance on some topics and maybe discover what we still need to agree on. Q0. **Nested Spaces in model** No matter the UI decisions we still need to take, we are implementing Nested Spaces for 7.2 roadmap. The future is still uncertain regarding changing the model to accommodate Nested Documents, since we can simulate ND using NS. Q1. **NS vs ND in the UI** Q1.1 The majority agreed that since the final purpose are ND, we should display ND in the UI, since it simplifies the mental model of the user. This implies removing the Space concept from the UI. Q1.1.1 A consequence is hiding the 'WebHome' name in the UI. Q1.2 Although the default should be ND, the question is if we want to give the option to display NS in the UI. This would be implemented as an advanced and technical option. The main problem is that we might need to provide UI alternatives for several components (menus, create step, etc.) Q2. **Parent/Child** Q2.1 Deprecate the notion of Parent/Child. Q2.1.1 Provide a migration to transform the relation into NS/ND. Problem: the old URLs[A] (bookmarks) are broken + the user is stuck with long URLs[B] if he wants to keep the hierarchy. Additionally we might need to provide an extension/configuration to transform into short URLs [B -> C]. Q2.1.2 Don't migrate: the parent/child hierarchy will be lost but the old URLs[A] (bookmarks) will be kept. The user needs to use NS/ND to create hierarchies. Q2.2 Don't deprecate the notion of Parent/Child. Q2.2.1 Provide a configuration in the Administration to switch the breadcrumbs between displaying Parent/Child or NS/ND. We might need to provide UI alternatives for several components (tree, breadcrumb navigation, create, etc.) Please cast your votes / add comments. Thank you, Caty
