hey sinar! this is not how you choose a nickname on joining a room, https://xmpp.org/extensions/xep-0045.html#example-18

to "to" attribute of your presence should be "room@server/YOURNICK"

I wish this were though.. but inside <{muc}x/> ✏

Hello

Hello, I am developing an XMPP client with java, Currently, I'm implementing XEP-0115. When I try to attach the form defined in XEP-0232: Software Information, I found no information to get the verification string for the Data form field of type XEP-0221: Data Forms Media Element. Is there any standard to implement this or do I just need to ignore this kind of field? Currently, I'm ignoring this kind of field as no documentation found. Thanks Al Masum Nishat

masum.nishat21, isn't that just xep115 § 5.1 step 7?

In that section it says only about values of a field, but for xep 221 media fields do not have any value. So i can not get verification string using 5.1 step 7 of xep 115

Media fields to have a value

221 just defines a way to make a media label for a field

The field is otherwise a normal field

singpolyma, I don't see a <value/> in xep221 ex2, what am I missing?

my first feeling is that xep221 data form fields are non-standard ✏

Data form field values are always optional

sure

(in the schema)

masum.nishat21, I am not sure why are are not able to get a verficiation string if you just blindly follow the instructions in step 7

especially step 7c

7)c)a) append the value *of the* 'var' attribute ✏

and be done, because 7)c)b) and 7)c)c) do not seem to apply because there is no <value/>

There is no where written in xep 221 that it may contain value elemant.

hmm?

masum.nishat21: it doesn't need to be, it's part of data forms xep

flow: now im doind it blindly.

221 just defines the new media label element

masum.nishat21, as singpolyma said, <value/> is optional and xep221 does not seem to specify one for data form media elements

so you can skip 7)c)b) and 7)c)c) for them, because there is no <value/> element

There may or may not be a value element, nothing to do with 221

exactly

I got it. I think that i should omit value if there is no one for that xep 221 elements.

There will be a value element if the field hrs a value, that is all

masum.nishat21: for all fields. 221 being present or not is irrelevant

Okay thanks for helping me. I got my solution.

but interestingly xep115 seems to be written with a <value/> being present in mind

which is probably not surprising, given that <value/> is how you transfer information

Right. Does it not distinguish between value not present vs empty value? ✏

I think at least one example is worth adding with value in xep 221

well empty value would be the empty string, woulnd't it? which you then would have to process as such

Right

masum.nishat21, that does not seem sensible, because the <value/> for xep221 element seems to be contained in <uri/>, if I am not mistaken

masum.nishat21: if you look at captcha xep you'll see media labelled fields which clearly expect the user to fill in a value

flow: no. The URI is a label not a value

ahh ok

Here was my doubt between value and uri

Yeah. If you remove the media element from a 221 adorned field it should still work the same

Just not have the image for the label anymore

The semantics of the existing elements from data forms are unchanged

singpolyma: I didn't find any field contains both media and value in xep 158 also

Which one is 158?

Captcha

All those fields expect a value from the user

They don't usually have an existing/default value though

I understand now. Thanks a lot.
