Single vs Multi-Value Label Categories in PS

Post by f.leyssens »

Hello Board,

I have a question re. the definition and control over what i would call 'Catalog Label Categories'.
It PS is quite easy to define your own Catalog Label Categories.
Since I noticed that it is possible to accidentally assign two labels from the same Category set to a picture I wonder if it is possible to prevent that from happening and distinguish between so called 'single value labels (properties)' where only one label from that set can be assigned to an asset and 'multi-value labels (properties)' where it makes sense to assign more than one label from the same category set.

Here is an example:
I have defined a label category called 'Model Name' for my products. Possible values are 'Seater', 'Lounger', 'Deluxe'. Since a specific product typically has only one model name it makes sense I should be able to only assign a picture the label 'Seater', OR 'Lounger', OR 'Deluxe' and not 'Seater' and 'Deluxe' as 2 tags for the same product model category. This is in other words a typical 'SINGLE value label (or property).
On the other hand I have also defined a label category called 'Market Name' for my products. Possible values are 'Home', 'Retail', 'Wholesale'. Since a specific product can be sold in different markets it is perfectly OK to assign both 'Retail' and 'Wholesale' as market tags for the same product market category. This is in other words a typical 'MULTI' value label or property.

I would like it to be possible to distinguish between these two label catgegory sets and make sure SINGLE value label catergories CANNOT accidentaly be given more than one label (tag) from the same category set. Is there any way (a setting) that makes this possible ??

Thank you very much in advancve to get back to me on this topic.

Best regards,

Frederik

Yes, there is - it doesn't work exactly as described by you, but it allows you to achieve more or less the same thing. Rather than set anything on 'Model Name', you have to edit the details of each model label (that is: 'Seater', 'Lounger' and 'Deluxe') and set the 'Unassign labels with same parent' property (it is disabled by default). Please note that you can do it for all three labels at once, by selecting them and right-click -> Details.

Two things to keep in mind:

1) Whenever you add a new model label under 'Model Name', you need to remember to change its 'Unassign...' property accordingly. (Not ideal, I know. Feel free to vote for feature request 2558 if you'd like sticky label settings; Mantis is the support system for Photo Supreme, btw.)

2) If you have 'Seater' already assigned to a image and you're assigning 'Lounger' to the same image, then I don't think PSU will prevent you doing that - it will simply replace the 'Seater' label by 'Lounger'. This may or may not be what you want - just keep it in mind.

Hope that helps,
Vlad

Hello again, Frederk!

Since this may not be obvious, I would like to point out that the PSU setting for unassigning sibling labels is arguably more powerful than a SINGLE-label property settable on the label container (that could be a label category or another label), because it also allows you to set only one (or several) sibling labels that must be exclusive, if you so desire.

I haven't needed this myself yet, but I'm trying to come up with a simple example. Let's say that you want to completely distinguish the Wholesale market from the Home and Retail markets. Then, you could set the 'Unassign...' property only on the 'Wholesale' label - this will enusre that any 'Market Name' image will eventually have assigned either the 'Wholesale' label only, or any combination of the 'Home' and 'Retail' labels (both or either one). That is very neat, isn't it!

This said, in a simpler (and typical) use case, you just want exclusive labels - and the fine-grained "Unassign..." setting may not be ideal here. Feel free to enter a feature request in Mantis for setting a SINGLE-label property on the label container (category or another property), I would vote for it! (Just keep in mind that a label hierarchy may have multiple levels, so there must be some thought given whether the new setting needs to propagate downwards, if it can be overriden, how will it interact with the current 'Unassign...' (if that's still to be manitained) etc; coming up with a logical and intuitive functional spec could get hairy, I guess, although it's not necessarily impossible.)

Regards,
Vlad
