Library – confirm preferred categorisation for HMO and LO

[brutaldigital]

Rob,

Please can you confirm that the categorisation of HMO as 'texts' is preferable to 'books'?

YCBA appears to use 'books' for HMO and 'texts' for LO.

HMO: https://linked-art.library.yale.edu/node/a67dc503-fcf5-44f0-92b2-cb3cf4a0799e
LO: https://linked-art.library.yale.edu/node/2897515f-2e5e-412c-97a0-f1908a6af87c

YCBA is correct here. If we know that it's a book format of object, then it would be better to have books on the HMO.

To confirm - Action for me here is to classify all Library LOs as texts (classified as type of work) and all Library HMOs as books (classified as type of object). Neither is happening atm.

[tomcrane]

Actually that's not true - the LOs are being classified according to the value of <medium> using this lookup:

https://github.com/tomcrane/linked-art-net/blob/pmc/LinkedArt/PmcTransformer/Library/Media.cs#L20-L35

[tomcrane]

So <medium>Text</medium> results in classified as "Text" https://vocab.getty.edu/aat/300263751
(25167 of these) - and lots of other media.

But no classification of HMOs, seems like at least some of these should be reallocated to the HMOs?
e.g., DVD->type of object

[tomcrane]

Leave open because we might get new values and rules - might need a combination of medium and class to determine classification.

Emma has made updates to the CLASS fields to better identify the medium. Revised values are:

<class>AUDIO VISUAL - SOFTWARE</class>
<class>AUDIO VISUAL - VIDEO</class>
<class>AUDIO VISUAL - AUDIO</class>

            //               to be applied to:      (the LinguisticObject, the HumanMadeObjects)
            MediaDict[InformationFiles.Label!]    = (Text, InformationFiles);
            MediaDict[Text.Label!]                = (Text, Getty.Book) ;
            MediaDict[ExhibitionCatalogue.Label!] = (ExhibitionCatalogue, Getty.Book);
            MediaDict[AuctionCatalogue.Label!]    = (AuctionCatalogue, Getty.Book);
            MediaDict[Journal.Label!]             = (Journal, null);
            MediaDict[CDRom.Label!]               = (null, CDRom);
            MediaDict[Website.Label!]             = (Website, Website);
            MediaDict[Manuscript.Label!]          = (Text, Manuscript);
            MediaDict[DVD.Label!]                 = (null, DVD);
            MediaDict[Microfilm.Label!]           = (null, Microfilm);
            MediaDict[CD.Label!]                  = (Getty.Sound, CD);

While I can now pick out when a DVD is software vs video - what should that produce in the linked art?
The code now passes the classes in when assigning a medium, so they can be used to further qualify it - just need to work out what to do there.
