Labels for Parts

[Kolophonium0]

Id would be nice, if parts could have some kind of label.

Thanks for this idea. Can you give an example?

@MartinFechner
Im creating an edition using Javascript wich uses parts to avoid always loading the whole document/object. Now i want to let the User know where in the document they are by displaying a title like <object label>/<partid> but then you are restricted by the ID format. Sure it would be possible to use a child node of the part for that purpose, but it would be more convenient to use the partlist returned by the api for that. Maybe having as partlist a list of objects like [{partID: partLabel}, ...].

To return also a label one can add a xpath definition for label to the parts definition in the appconf.xml. Then it can be used here:

ediarum.WEB/content/edweb-api.xql

Line 161 in 91cf7b7

let $ids := util:eval-inline($d-map?xml, $xpath)

and here:

ediarum.WEB/content/edweb-api.xql

Line 167 in 91cf7b7

let $ids := util:eval-inline($xml, $xpath)

with something like

 let $labels := util:eval-inline($xml, $label-xpath) 

Beware: The recursive funktion list-part-ids isn't very performant if a large document is used in combination with a three-or-more level hierarchy (like: book1.chapter1.section1). It maybe becomes worse if the label evaluation is added.
