Name: Kate Bowers Affiliation: Harvard University Library Does this represent an official comment from your affiliated group? Yes Comment: Use of <daoset> for thumbnails embedded in finding aids?

I wasn't sure if <daoset> was envisioned as the mechanism for embedding
thumbnails with links to resources in EAD. I assume a clever stylesheet
could turn the following example into an embedded image that becomes a
clickable link to the resource.

` <dao daotype="other"
href="nrs.harvard.edu/urn-3:HUL.ARCH:kate?height=250" localtype="thumbnail"
show="embed">

Full size image is available online.

 </dao>
 <dao daotype="borndigital"  

href="nrs.harvard.edu/urn-3:HUL.ARCH:kate?buttons=y"/> `

Need to review daoset/dao to make sure attributes are sufficient to capture thumbnail to object linking, include examples in Tag Library.

I think that we are OK with <dao> as it is to support think thumbnail to object linking. We added @label to <dao>, primarily because we wanted to bring it in line with the other children of <did>, but in the <daoset> context it could be used to indicate label="Thumbnail" or label="Object" (whatever makes sense). Or a shop might use daotype="otherdaotype" and otherdaotype="thumbnail". Either way, a style sheet could then know to embed the first and link it to the latter. @show and @actuate help with this as well. What won't work is wrapping multiple pairs of thumbnails and objects into <daoset>, but I don't think that worked in <daogrp> either.

The primary piece of linking information that we are losing in the <daoset> model is the <arc>, which includes @from and @to to indicate linking sequence. I'm happy to push that off to style sheets. And in a context where someone takes someone else's EAD and doesn't know how exactly to sequence <dao>s within <daoset>, I think it will degrade gracefully as long as the show and actuate attributes are correct.

Not closing this yet, but marking it documentation. Will need to include examples of how to use <daoset> to embed a thumbnail that links to an object. Will want to think more about how exactly to do that, but I think there are only a few options.

Just a note, perhaps it could be of help: In the Archives Portal Europe we are only using repeated <dao> elements, not <daogrp> and we do have partners who provide links to thumbnails as well as links to higher resolution or other presentation forms of their digitial objects. We differentiate these two version via the xlink:title attribute at the moment that would have the value "thumbnail" in case the accompanying xlink:href provides the link to the thumbnail. By this and by the direct sequence of higher resolution <dao> and thumbnail-<dao> it's possible (and hasn't given us too much of a headache so far) to display the thumbnail in the Archives Portal Europe and to use it as a link to the higher resolution image (see e.g. http://www.archivesportaleurope.net/ead-display/-/ead/s/C37644135/0/remissorium).

@kerstarno Great to know. That adds to my resolve that we are right to shift from daogrp to daoset. Thanks.

@kerstarno https://github.com/kerstarno: thanks for the info. Very helpful. Perhaps we could provide examples along these lines in the TL.

Need example of a with two s - one with localtype set to thumbnail, another with fullsize or some other local terminology.

Example included in TL.
