[non-taxonomy discussion thread, interim update]
I like to summarize the changes so far
per comments and research on the latest data in previous cases:
1) libsane APIs and libsane.so upgraded to Committed.
2) SANE utilities upgraded to Uncommitted.
3) Remove dependency on Gnome, libtiff and libjpeg as they are
Committed interfaces now according to the new
interface taxonomy. It is unnecessary to explicitly list
Committed interfaces in the proposal.
64-bit issue and the corresponding libusb CR will be added to the text
in the final spec.txt.
Best Regards,
T.Paul

> Summary
> This project integrates libsane and sane into Solaris.
> This project requests a minor binding.
>
> 4.1 Details
>
> SANE is an application programming interface (API) that provides
> standardized access to any raster image scanner hardware. The
> standardized interface makes it possible to write just one
> driver for each scanner device instead of one driver for each
> scanner and application.
>
> SANE is clearly separated into applications(frontends) and scanner
> drivers(backends). A SANE backend provides an interface with the
> hardware and describes a number of options which drive each scanner.
> sane, in this proposal, refers to applications that
> are delivered by SANE community, http://www.sane-project.org/.
>
> "sane-backends" package of FOSS project SANE contains backends,
> documentation, networking support and the command line frontend
> "scanimage".
>
> In this project, the following components will be ported and
> integrated into Solaris:
>
> 1)sane-backends
> sane-backends contain drivers for popular scanners on the
> market. This project proposes to only support local USB
> scanners.
> As an effort to enrich desktop applications for Indiana,
> SANE network feature is not considered essential and hence
> out of scope for this project. A future case may support
> this functionality.
>
> 2)libsane
> Standard SANE APIs are provided by libsane. Different
> frontends are developed on the base of such set of API.
>
> 3)sane documentation
> User manuals.
>
> 4)scanimage
> scanimage is a command-line interface to control image
> acquisition devices. It is one of the SANE frontends.
>
> 5)xscanimage
> xscanimage provides a graphical user interface to control
> an image acquisition device such as scanner. It allows
> previewing and scanning individual images.
>
> SANE depends on the scanner's device special file for access control.
> For USB interface scanners, by default only users on console or
> superuser have permission to access the devnode, which is controlled
> by logindevperm(4). It is also possible to restrict access to a
> scanner using Solaris device allocation subsystem. Sysadmin can enable
> BSM and put scanner device special file (exported by ugen(7D)) in
> device_map and device_allocate(4), so that the scanner is allocatable
> and then can be used by only one qualified user at a time.
