Scoring of dash:TextFieldWithLangEditor

[Tomasz Pluskiewicz]

Hello

We've looked at the scoring and implementation of dash:TextFieldWithLangEditor and find the rules a little inconsistent.

Particularly, it seems that 5 will never be returned because if rdf:langString is permitted, the  first run will always be hit and score = 10 returned.

Also, why exclude dash:singleLine from this editor?

Best,

Tom

Hi Tom,

On the first topic, maybe the wording needs to be clarified, but the two cases are different:

10 is only returned if the widget is for an *existing* value, and that value is a rdf:langString literal

5 is returned for new "empty" values, e.g. on a yet unfilled form, and the property does not exclude langString

On the singleLine you are right, this looks like a bug: It should say that dash:singleLine != false. The intent is that if someone explicitly states singleLine=false then the TextAreaWithLang should be preferred. I have just fixed this, both in the spec and in our code and see how it behaves.

Does this make sense to you?

Thanks
Holger

Hi Holger

Yes, thank you.

I’m combing up with a follow up, having actually implemented this in our forms. Consider a shape which has `sh:datatype rdf:langString` and a value which is a plain string literal. Both single line editors will get a score = 10. This can cause an underterministic behavior where one or the other comes on top.

I think that a property which is explicitly constrained to tagged string should actually prefer the lang editor over plain text box.

Best

Tom

Hi Tom,

makes sense (although this is a bit of a corner case since the value violates the constraint). I have changed

    http://datashapes.org/forms.html#TextFieldWithLangEditor

to go from 10 to 11. I also clarified that both xsd:string and rdf:langString must be allowed (sh:or) as datatypes.

Does this look better to you?

Thanks,
Holger

Looks great. Thanks
