How fast ?

Checking XMPP

is there a way for the server marking a pubsub node as read-only?

lovetox, I am not aware of such a marking (but it's pubsub, so it may be somewhere). May I ask what an entity would do with that information, e.g. how it would influence an entities behavior?

say you have a server connected to ldap

the server provides vcards with information filled by ldap

now as a client you show that vcard, but you cant show the user that he is not able to edit that vcard

Is there anything like that anywhere else?

Mostly I think we return an error when you try

i mean it would probably trivial to hack something together that shows that to the client

just add a custom attribute to the vcard

that says LDAP, or Read-only

whatever

hmm I wonder if it would be sensible to have an is-this-pubsub-node-modifiable-by-me IQ query

not sure if a server could mark a node as such

which would be preferable, of course

hmm, but can't you query the node settings and see if you can modify it?

flow there is no setting that would forbid me to modify my account pubsub node

as account, i have full publishing permissions on anything

lovetox, I would imagine that a service would not allow you to modify a read-only pubsub node (e.g. like a synthesized vcard from ldap, as per your example)

so maybe a service could set the access model to whitelist, with the list being empty

surely in such a deployment, not having write access would be fine

ahh wait, "access model" seems to be about notification access, not push access

flow, i never queried the whitelist

but i imagin it is always empty

yeah anyway

Zash, sure, the question was how a client becomes aware of this. without the client presenting a user a nice dialog where he can modify the node, only to be annoyed to learn that he is not allowed to modify it

Some kind of "who am I to you" query would be nice.

Hm, do current PEP implementations do https://xmpp.org/extensions/xep-0060.html#entity-affiliations ?

how would that help Zash?

could tell you whether you're _not_ the owner of some node, or otherwise don't have an affiliation that gives publishing rights

oh

then i would do this query

https://xmpp.org/extensions/xep-0060.html#owner-affiliations

and see that im for example only member

hm but can a member retrive the affiliations ^^ ✏

Confusingly there are two <affiliations/> queries, a normal one and an #owner one.

no the one you pointed to gives all the affiliations a service offers

The former lets you query a pubsub service for your own affiliations (for all nodes on the service)

ah

ok

i understand

ok i guess this solves the problem thanks

probably as close as we get without inventing some new feature, yeah
