JPSearch is explained (incl. papers) at https://jpeg.org/jpsearch/index.html
From the recent JPEG Press Release at https://jpeg.org/items/20150206_press.html
"JPEG has been making continuous efforts to further
extend interoperability and usability of the existing JPSearch
standard of image search and management framework. As a result,
JPEG is proud to announce that the technical development of JPOnto
as an amendment of JPSearch Part 2 and JPSearch API as an
amendment of JPSearch Part 3 are finalized and approved by the
national bodies and now await formal publication. JPOnto provides
an expandable vocabulary for describing images - or objects in
images - in RDF (Resource Description Framework). A formalized
vocabulary provides a standard for rich image annotations that
can be interlinked with external resources and as such vastly
improves interoperability. In addition, JPOnto specifies how
these descriptions can be embedded within the image itself to
guarantee the portability. The JPSearch API on the other
hand simplifies how mobile or web-based applications interact with
images and image collections by specifying a REST based interface.
The API offers a standardized interface for client-server
communication for apps that provide features such as metadata
based search, searching for visual similar images or requesting
automated image annotations. In order to fulfill mobile
development needs, the interface is lightweight to minimize
bandwidth usage and can be flexibly integrated with other APIs."
Any feedback on commonalities and differences with FAST developments
on music search would be appreciated.
