After digging around in the sling code a bit I found the ContentReader
interface, with Json, Zip, and XML reader classes.
This looks looks like the right option, IOW implement a new ContentReader class
for my data type.
The one remaining question is, how does this tie in with the content type
detection on the front end?
I am setting up the mimeType for this extension already:
mimeTypeService.registerMimeType("application/vnd.adobe.folio+zip",
"folio");
but what else do I need to do to invoke the new ContentReader once this
mimeType is detected?
I see the existing loaders are all defined in BaseImportLoader. Is there an API
to append new extension/loader mappings to this?

Subject: Defining new content types and associated import actions
I keep finding that I’m doing things the hard way and that someone has
already thought of this and has implemented something far better than my
current attempt. Therefore I have to ask this question.
I need to import content with a well defined structure adobe multi-folio
archives. These are zip files consisting of an xml content descriptor, a
mime type file and a number of child folio archives.
Folio.xml
mimetype
0000_Cover.folio
0001_article_xx.folio
0002_artivle_yy.folio
…
The mime type contains:
application/vnd.adobe.folio+zip%
where each child .folio file is a zip consisting of another folio.xml
descriptor file and additional media files:
├── Folio.xml
├── META-INF
│ └── pkgproperties.xml
├── StackResources
│ ├── asset_L.pdf
│ ├── asset_P.pdf
│ ├── scrubber_L1.jpg
│ ├── scrubber_P1.jpg
│ ├── thumb_L1.jpg
│ ├── thumb_P1.jpg
│ └── toc.jpg
└── mimetype
Is it possible to define a new content type for each of these, the parent
multi-folio and the child folio structures such that when I post using
something like:
curl -u uid:pwd -F":contentType=multifolio" -F":operation=import"
-F":contentFile=@~/bedge/issue.multifolio<mailto:contentFile=@~/bedge/issue.multifolio>"
http://localhost:8080/content/issue
that the behavior would be to unpack the multifolio, then upon discovering
the child .folio files, and recognizing the registered format for these,
also unpack each of these?
The gravy would be to also parse the folio.xml files and validate that all
resources defined in the xml are indeed present, but I admit that’s
getting greedy.
