This is a project based on the work of Fr Seraphim Dedes. The goal is to create on demand texts based on the needs of a particular community and resources to help chanters with learning chant. This is from their initiatives page:
AGES Initiatives envisions all Orthodox Churches having the texts, music, and trained singers needed to maintain the fullest possible liturgical life. To that end, it is developing a multilingual database, rubrics engine, and applications for church, home, and classroom, as well as translation tools for use in the mission field.
AGES™ is a software platform that will store, organize, and deliver Orthodox Christian liturgical texts and music to support the education of church singers, and to facilitate the smooth performance of church services, using current and emerging technologies.
With the blessing of Metropolitan Alexios of Atlanta, AGES Initiatives, Inc. was founded as a nonprofit corporation by Fr. Seraphim Dedes, best known for ematins.org, which supplies free liturgical texts and music to churches worldwide
