+@uref{https://summerofcode.withgoogle.com/, GSoC} is a global program
+that offers students stipends to write code for free software and open
+source projects during the summer. For three months students work to
+complete a given task as part of the project's community and under the
+guidance of experienced mentors. The program is an excellent
opportunity for students to gain experience with real-world software
development and make a contribution that benefits everyone. It brings
new contributors to LilyPond and enables students who are already
involved to become more involved. LilyPond participates in GSoC as part
of the @uref{http://www.gnu.org/, GNU project}.
-We have had GSoC participants in 2012, 2015 and 2016 and encourage students
-to apply for future summers.
+We have had GSoC participants in 2012, 2015 and 2016 and encourage

-we will help you find a mentor for a project that fits your interests
-and skills.
-
-If you have ideas for a GSoC project that is not listed below you can
-send us an email as well. There are a number of areas where LilyPond
-could be improved, and our development team is always willing to help
-those who would like to tackle a project like those listed below.
+Below is a list of GSoC project ideas (last update: January 2017), but
+if you have other ideas for a project you may complete within the three
+months of the program you're welcome to make a suggestion on our
+developer mailing list (see @ref{Contact}). There are a number of areas
+where LilyPond could be improved, and our development team is always
+willing to help those who would like to tackle a project similar to
+those listed below. As mentor availability varies from project to
+project and from year to year it is wise to get in touch with us as
+early as possible.

-@subheading Grace notes
-
-Fix problems with synchronization of grace notes. Grace notes can
-interfere with LilyPond's timing and cause odd effects, especially when
-multiple staffs are used where some have grace notes and others don't.
-This is one of the longest-standing and one of the more embarrassing
-@uref{https://sourceforge.net/p/testlilyissues/issues/34/,bugs} in
-LilyPond.
+@subheading Contemporary Notation
+
+LilyPond is very good at creating non-standard notation. Having to
+@emph{code} every graphical element instead of simply @emph{drawing}
+it may seem cumbersome but is in fact a strong asset. New notational
+functionality can be provided with consistent appearance, automatic
+layout and a natural syntactic interface.
+
+Within the @uref{https://github.com/openlilylib/oll-core, openLilyLib}
+library system the student will create a fundamental infrastructure
+and building blocks to make creating contemporary notation easier.
+Additionally (at least) @emph{one} concrete package is developed to
+cover specific contemporary notation, such as for example the style
+of a given composer, extended playing techniques for a specific
+instrument or a certain category of effects.

-on context and neighbor notes (see section 2.2 of
-@uref{http://imslp.org/wiki/Repository_of_Music-Notation_Mistakes_%28Coulon%2C_Jean-Pierre%29,
-this book}). If possible also reduce beaming-computation time.
+The @uref{http://ooolilypond.sourceforge.net/, OOoLilyPond} extension
+made it possible to conveniently include LilyPond score snippets in
+OpenOffice.org/LibreOffice Writer, Draw and Impress documents while
+keeping source and image together. After many years without development
+an initial effort has started to make the extension compatible again
+with current versions of LibreOffice and LilyPond.

+However, as the LibreOffice ecosystem has changed substantially it is
+now possible to rewrite the extension with Python and PyQt. This will
+not only be more powerful in general but will allow the integration of
+functionality from @uref{http://frescobaldi.org, Frescobaldi}, such as
+for example syntax highlighting, entry helpers, score wizards or musical
+transformations.

-@subheading Help improve compilation behavior
-
-Automatic code analysis tools, like valgrind memory leak detection or
-callgrind code profilers, provide valuable information about possible
-flaws in our C++ code. Cleaning up warnings would allow us to automate
-the rejection of any patch which introduced extra warnings.
+@subheading Automated testing and documentation for openLilyLib
+
+@uref{https://github.com/openlilylib, openLilyLib} is an extension
+framework for LilyPond code providing a “snippets” repository and a
+suite of integrated packages such as for example page layout tools or
+scholarly annotations. It is very powerful and promising, but to really
+get off the ground two features are missing: automated testing and
+documentation generation.
+
+Automated testing is necessary to ensure modifications to functionality
+don't break other functions within the library. There is already some
+Automated Testing of the “snippets” repository with Github's Travis
+server, but this has to be reconsidered and extended to cover the
+standalone packages too.
+
+In order to be usable for a wider range of LilyPond users on a “consumer
+level” openLilyLib needs proper documentation. This documentation has
+to be generated from the sources, so a system is needed that requires
+package authors to document the input files and provide additional usage
+examples, from which documentation is generated. Ideally but not
+necessarily this is implemented as a Git hook, i.e. automatically upon
+each update to the repository. We don't prescribe the tools and
+approaches to be used, but the most widely used language in the LilyPond
+domain is Python, so there would be some bias towards that.
+Alternatively a Scheme solution could be fine so generating the
+documentation would actually be triggered by “compiling” a certain
+LilyPond input file. In general it is advisable to make use of proven
+concepts and tools from other languages.
+
+The eventual output of the documentation should be a static HTML site
+that can be viewed locally and/or uploaded to a website. But it would
+be beneficial if the tool would first generate an intermediate
+representation (e.g. a JSON file with additional media files) from which
+a Single Page Application could retrieve content for display on
+openLilyLib's @uref{https://openlilylib.org, website}. Development of
+such a SPA @emph{can} be part of the GSoC project, but is optional.
@strong{Difficulty:} medium
-@strong{Requirements:} C++
-@strong{Potential Mentors:} Reinhold Kainhofer (not available for GSoC

Improving MusicXML import and export functions:
-@divClass{keep-bullets}
-@itemize
+File interchange between LilyPond and other applications using MusicXML is still
+a difficult matter. To import MusicXML it has to be converted manually by
+mysicxml2ly. Export is only available as midi file or as a rudimentary feature
+inside Frescobaldi. In order to provide natural interchange between LilyPond
+and MusicXML-based applications there's need of an import functionality
+and an export backend.
-@item
-Handle basic musical content export like the MIDI export (i.e. using
-dedicated exporter classes, derived from the translator class).
+Importing XML shall provide file, line and column to add origin-attributes to
+generated objects. That way point and click can be made available in Frescobaldi
+or other supported IDEs.
-@item
-Build the XML tree of the basic musical content, add a connection from
-music event to XML tag.
+Exporting XML shall be realized with an exporter class like the Midi export.
+This may be based on the work already done in
+@uref{https://github.com/DavidGarfinkle/Lilypond_MusicXMLexport, GSoC 2015}
+by David Garfinkle. It should be checked, if it is suitable to use another
+XML-library than the one provided by guile-2, so that this feature is
+available in current LilyPond - based on guile-1.8.
-@item
-Let all LilyPond engravers do their job.
-@item
-Link each output object (i.e. each stencil or group of stencils) to the
-music cause (and thus to the XML tag in the XML tree).
+@strong{Difficulty:} medium
+@strong{Requirements:} MusicXML, Python, Scheme, basic LilyPond knowledge
+@strong{Recommended:} Familiarity with other scorewriters (for cross-testing)
+@strong{Mentor:} Jan-Peter Voigt
+
-@item
-Add an XML output backend, which can then add layout information for
-each output object to the XML tags.

-There are several possibilities for this project, including building upon
-the MusicXML export project from GSoC 2015.

+In order to have a satisfying experience with GSoC applicants are
+strongly advised to thoroughly read the following recommendations. Some
+of these are relevant for the application process, others for the time

-@subheading Improve slurs and ties
+@item
+Please get in touch with us as soon as possible if you are interested in
+applying with a project. Mentor availability may change without notice,
+project proposals may need fine-tuning, and many other reasons might
+require us to reject or ignore an application that hasn't been discussed
+before.
-The engraving quality of slurs and ties is often unsatisfactory. Ties
-@q{broken} by clef or staff changes are not handled well. The project
-could include collecting and sorting examples of bad output, deciding on
-the intended output and writing code to improve them.
+@item
+We do not know in advance how many “slots” we will have available for
+projects, so please be aware that you may find yourself in competition
+with other applicants or not. Interested or even enthusiastic response
+from our mentors is no guarantee of eventually being accepted, and
+@emph{not} being accepted does not necessarily indicate a negative
+evaluation of your application. If we have to decide between different
+applicants there may be various aspects to consider.

+@item
+Integration in the LilyPond community is a fundamental part of GSoC, and
+we expect our students to make substantial efforts to become community
+members. Within the @emph{bonding period} we expect you to write a blog
+post about your project (either on @uref{http://lilypondblog.org, Scores
+of Beauty} or on any other blog) and to be active on our mailing lists,
+introducing yourself but also communicating about unrelated tasks. This
+goes beyond the mere setting up of a working environment and
+familiarizing yourself with the relevant code, but we think it is
+crucial for the GSoC project to be mutually satisfying.
-@divEnd
+@item
+If you are accepted to the program you will have one mentor explicitly
+assigned to your project. With this mentor you will have to agree upon
+a communication strategy, be it emails, chatrooms, issue trackers or
+voice/video chats. Regular communication is absolutely crucial for the
+success of a GSoC project so you are stricly required to keep talking to
+your mentor. But keep in mind that your mentor has explicitly taken
+over the responsibility for your project, and while unlike you he isn't
+paid for this activity you are still entitled to get regular attention
+from him.
+
+@item
+In order to get support from your mentor you have to give him a chance
+to follow your progress and efforts. Therefore it is important to
+regularly commit your changes to the versioning repository you are
+working on. Don't hesitate making unfinished code available because you
+are afraid of criticism, and don't suppress questions because you think
+they might be considered stupid. But ideally your code should at any
+time be accompanied by compatible testing code. Your mentor may not be
+able to properly assess your code by only @emph{reading} it without the
+opportunity to apply it in a real example.
