@subheading What is Google Summer of Code?
-A global program run by Google that offers students stipends for working
-on open source software projects during summer vacations.
-
-It is an excellent opportunity to find new contributors, and encourage

-involved. One of our contributors was accepted in the 2012 program as

-@subheading Our Ideas List
+@uref{https://developers.google.com/open-source/gsoc/, GSoC} is a global
+program that offers students stipends to write code for free software
+and open source projects during the summer. It 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}.
-Below is a list of projects that were suggested for the GSoC 2012
-students and is retained here as an inspiration for anyone
-who is interested in developing LilyPond for future GSoC projects.
+We have had GSoC participants in 2012 and 2015 and encourage students to
+apply for future summers.
-There are many more things that can be done to improve LilyPond and
-members of the LilyPond development team are always willing to help
-those who would like to tackle projects such as those listed below.

-Improving MusicXML import and export functions:

-dedicated exporter classes, derived from the translator class).

+@subheading Improve internal chord structure
-@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).
+The internal representation of LilyPond chords is not powerful enough
+to capture the nomenclature of jazz chords. Currently the chord has
+a root, a bass and an inversion. It would be nice to be able to handle
+stacked or polychords, minor/major, etc. In order to do this, an
+internal representation with the ability to capture the essence of
+complex chords must be developed. As a bonus, once the internal
+representation is developed, the output formatting of chord names can
+be improved.
-@item
-Add an XML output backend, which can then add layout information for
-each output object to the XML tags.
+@strong{Difficulty:} Easy/medium
+@strong{Requirements:} Scheme (Guile), but the level necessary can be
+easily learned

+@subheading ScholarLY
-Familiarity with other scorewriters (for cross-testing) would also help.
+ScholarLY is a library in
+@uref{https://openlilylib.org, openLilyLib} that provides functionality
+for annotating scores, making it possible to manage scholarly workflows
+completely in the context of the score document. So far it is possible
+to enter annotations of different types, produce clickable messages in
+the console output and export to text and LaTeX files.
+There are numerous feature requests to turn this library into an
+even more powerful and comprehensive tool. Some examples: Inserting
+music examples, producing footnotes, automatically applying styles
+to the annotated item (e.g. dash a slur, parenthesize an accidental),
+creating reports with point-and-click entries. For a full description
+of this project suggestion please visit

+@subheading Allow spanners to cross voices
+Currently all sorts of spanners (ties, slurs, dynamics, text spanners,

+this doesn't reflect the reality of notation in most polyphonic settings.
+Awkward workarounds with hidden voices are currently necessary to achieve
