Reqt - serendipitous discovery via membership of IIIF collections
(tag-based browsing - this kind of thing: http://iangilman.com/openseadragon/flickr/)
This is not part of the IIIF spec, as it isn't presentation semantics. It would be really useful to add an extra piece of metadata to tell me why a resource is a member of a particular collection.
{
"@id": "http://wellcomelibrary.org/iiif/b21539054/manifest",
"@type": "sc:Manifest",
"label": "The cocktail book : a sideboard manual for gentlemen."
...
"within" : [
{
"@id": "http://wellcomelibrary.org/service/collections/topics/Cocktails/",
"@type": "sc:Collection",
"label": "Cocktails",
"xxx" : "yyy" // something that tells my bespoke system that this is a LC Subject Heading
},
{
"@id": "http://wellcomelibrary.org/service/collections/topics/Liquors/",
"@type": "sc:Collection",
"label": "Liquors",
"xxx" : "yyy" // something that tells my bespoke system that this is a LC Subject Heading
},
{
"@id": "http://wellcomelibrary.org/service/collections/authors/12345",
"@type": "sc:Collection",
"label": "Knowles, Frederic Lawrence"
"xxx" : "yyy" // something that tells my bespoke system that this is a collection of the author's works
}
]
}
See IIIF/api#438
This is not the same thing, but is relevant.
Maybe all that is required (this is presentation only) is a further "within" to one of the (presumably limited in number) top level collections, whose URIs would be recognised by a consuming system. My tag browser knows that http://wellcomelibrary.org/service/collections/authors means authors and therefore that
manifest within an-author within authors
...should generate UI that suggests that an-author is the author of manifest

Maybe that's all I need to drive a tag browser? My system recognises the URIs of the nested within properties, therefore it knows that the first two are topics (subject headings) and the last is the author.
