EtoileUI Difficulty:

EtoileUI is a reflective UI framework based on a uniform tree of UI objects, it implements many Étoilé high-level UI features like Pick & Drop, Pluggable Layouts, Composite Document etc. This is a broad project which will involve working with Quentin on finishing the design and implementation of EtoileUI.

Time to Complete	Task
TBD	For a task list, see the TODO document.

Opal Difficulty:

Opal is the CoreGraphics implementation in Étoilé subversion.

Time to Complete	Task
4 Months	Finish the text-related functions in Opal and build a CoreText implementation on top (probably using Pango for most of the layout). This is a large task and probably should only be attempted by someone already familiar with Apple's Quartz and Cairo.

Theming Difficulty:

Finish existing Étoilé themes, and collaborate with GNUstep on the theme engine.

Time to Complete	Task
2 Months	Polish GNUstep theme engine.
1 Month	Finish Narcissus.
2 Weeks	Finish Nesedah.
1 Month	Finish the Aristo port.

OMeta Implementation Difficulty:

OMeta is a object-oriented pattern-matching language. It allows implementing parsers that can easily be extended by subclassing. Étoilé already has a work-in-progress implementation of the parsing side written in Smalltalk.

Time to Complete	Task
TBD	Finish the present OMeta implementation.
	Reimplement the present lemon-based Smalltalk parser using OMeta.

TermX Difficulty:

Finish the terminal application TermX (add colour support and other missing features)

Time to Complete	Task
TBD	TBD

SystemConfig Difficulty:

Write the missing parts of SystemConfig, test it on more platforms and implement missing components and write a dæmon which coordinates the access to the system, monitors the system and sends distributed notifications.

Time to Complete	Task
TBD	TBD

XMPPKit Difficulty:

XMPPKit is an Objective-C implementation of the Extensible Messaging and Presence Protocol (XMPP) that can be used to write Jabber-enabled applications.

Time to Complete	Task
TBD	Add Jingle support to XMPPKit. The Jingle protocol is a large collection of XEPs, so this can be done in an incremental fashion.
TBD	Add file transfer support to XMPPKit. Since the latest file transfer protocols are based around Jingle, this could be combined with adding Jingle support.
TBD	Implement shared shelf using PubSub (includes implementing PubSub - XEP-0060). The publish-subscribe protocol is very large, but only a subset needs to be implemented. The scale of this project can vary depending on the student.
TBD	Implement serverless messaging (XEP-0174). This will require some changes to the connection handling code in StepChat (which is badly in need of rewriting) and the abstraction of the presence handling code to allow presence stanzas to be delivered over ZeroConf.

PhotoManager Difficulty:

PhotoManager is a simple application for managing photographs, written in Smalltalk using EtoileUI and CoreObject.

Time to Complete	Task
2 Weeks	Implement stack/unstack operations similar to Aperture. They would give an "exploded" view of a group, by switching the layout set on it. For the "exploded" view, the layout would a either ETFlowLayout or a new ETSpreadStackLayout (based on ETComputedLayout).
1 Week	Add a full-screen layout to EtoileUI to support viewing a slideshow of the images.
2 Weeks	Add support for importing images from a digital camera, using the gPhoto library. Write both a simple Objective-C wrapper around gPhoto, and a CoreObject subclass which presents the photographs on the camera as a CoreObject group.
1 Month	Support reading image metadata, likely by writing a wrapper around an existing metadata reading library (support EXIF and IPTC, and possibly XMP).

Garnet-style Constraint Support for EtoileUI Difficulty:

TBD

Time to Complete	Task
TBD	TBD

Melodie Difficulty:

Melodie is the Etoile music player/manager. This project will involve various improvements to the application to bring it to a more usable state.

Time to Complete	Task
1 Month	Finish writing parsers for various playlist formats (M3U, SMIL, XSPF)
1 Month	Finish the album cover support. This will involve working with EtoileUI to support asynchronous loading of images.
1 Month	Integration with Last.FM, or possibly other web services.
1 Month	Support for iPod and other digital audio players.
1 Month	Investigate adding the capability to CoreObject to coordinate transcoding between different audio formats

CoreObject Difficulty:

CoreObject is a framework for managing persistence, versioning, and metadata on documents/objects. This project could cover a wide variety of work on CoreObject depending on the contributor's interests.

Time to Complete	Task
TBD	For task list, see the TODO document

Metadata and CoreObject Difficulty:

Investigate a unified way of handling metadata extraction, linking with UTI's (Uniform Type Identifiers). We have some basic code for reading audio file metadata in Mélodie, and will want to support reading metadata for other file types (video, photographs, etc.). We may want to support Adobe's XMP metadata format.

Time to Complete	Task
TBD	TBD

EventKit on top of CoreObject Difficulty:

The EventKit API that Apple introduced with 10.8 is very simple, and now that we have declared properties working with clang it would be pretty simple to implement it on top of CoreObject. Parsing iCalendar files is pretty simple (they're like vCards; trivial key- value pairs, you can parse them with NSScanner). Leave the remote calendar source stuff for now, and let people provide plugins for things like CalDAV / MS Exchange calendars if they're sufficiently motivated.

Time to Complete	Task
TBD	TBD

EScript Difficulty:

Work on EScript, an ECMAScript-like language implemented on top of LanguageKit.

Time to Complete	Task
TBD	TBD
