-## Improve multi-lingual scalability

-When organisations operate in multiple languages and have public-facing forms available in multiple languages,
-CiviCRM has to be switched to "multi-lingual mode". This makes it possible to translate custom field labels,
-contribution page titles, etc, into more than one language. However, the current database model is made in a
-way that only makes it possible to use up to 3 languages. We are looking to change the database model to a
-more scalable one.
-Technically, the current database model uses one big table per entity, with an extra column for each language
-(ex: civicrm_contribute.title_en_US). A MySQL "view" is then created to simplify database queries
-(civicrm_contribute_en_US.title). The model needs to be flipped around: an extra table for each language. We
-also need to provide an upgrade mechanism for existing sites.
+## Pluggable data export formats for reports
 
+Potential Mentor: Mathieu Lutfy (Coop SymbioTIC)
+
+CiviCRM currently supports exporting reports to CSV and PDF format. Some
+extensions make it possible to export to other formats, such as for exporting to
+Excel (xlsx), but they have to implement odd hacks to get around the lack of
+pluggable data export formats in CiviCRM.
+
+This project would therefore aim to provide a clean set of 'hooks' so that
+extensions can support other export formats. It would also aim to propose
+changes to some of the extensions, to provide examples. Since this is a change
+to CiviCRM's core, it would require writing a unit test, documentation and
+interacting with other developers to gather other potential use-cases for this
+hook.
