No PDF download for PDF files with single pages or chapters in logical structural map

[stweil]

Pointers to PDF files (mets:fptr) can be contained in the physical or in the logical structural map (mets:structMap).

The DFG viewer and Goobi.Presentation offer a download link for the whole work, no matter whether the PDF file pointer is part of the physical or of the logical structural map.

They don't offer a download link if the file pointer is only part of the logical structural map (<mets:structMap TYPE="LOGICAL">). This is the standard used by Visual Library, see http://digi.bib.uni-mannheim.de/ubmadesb/oai/?verb=GetRecord&metadataPrefix=mets&identifier=17198 for an example.

Update 2015-04-15:

File pointers in the logical structural map are typically used for PDF files which cover a whole chapter, but sometimes also only a single page, so maybe depending on the page range a "Download single page" or a "Download part of work" might be adequate.

This would be a (useful) new feature for both DFG viewer and Goobi.Presentation, not a bug fix.

SUB Hamburg uses Goobi.Presentation and offers PDF downloads for chapters (e. g. http://www.sub.uni-hamburg.de/nc/recherche/elektronische-angebote/digitalisierte-bestaende/trefferliste/seitenansicht.html?tx_dlf[id]=16117&tx_dlf[page]=1&tx_dlf[pointer]=0#grosse-ansicht). With the DFG Viewer (http://dfg-viewer.de/show/?set[mets]=http%3A%2F%2Fmets.sub.uni-hamburg.de%2Fgoobi%2FPPN839959273), no PDF downloads is offered.

With the DFG Viewer (http://dfg-viewer.de/show/?set[mets]=http%3A%2F%2Fmets.sub.uni-hamburg.de%2Fgoobi%2FPPN839959273), no PDF downloads is offered.

In the METS-file of this example, there is no hint to a PDF file at all. Kitodo.Presentation and the DFG-Viewer have no chance to present a link to these files.

This example is presented at the SUB Hamburg now at the following address: https://resolver.sub.uni-hamburg.de/kitodo/PPN839959273. There is only a work download on the right. And this seems to be an extra service based on the identifier.

So things may have changed in the last 5 years. Maybe there is a better example to follow?
