An ever increasing number of members of educational communities engage in creating new digital resources within all fields of science and practice at all educational level within Learning Object Repositories, which, in terms, allows for even more efficient identification and delivery of existing material. This has in effect shaped a new type of activities related to the creation, sharing and re-use of learning objects through distributed repositories, associated within a federation with common policies, protocols and formats, which gave rise to an exponential growth of available material. However, this great success brings along a set of challenges, the most important being the demand for a quality controlled process, eliminating the information overload and safeguarding the added-value of learning object repositories, through models such as peer review and validation of learning objects and associated metadata. The authors of this paper provide insight on the approach for capitalizing on the European and international demand for quality-controlled educational content on Organic Agriculture and Agroecology, describing a framework and the associated quality issues for modeling the publication lifecycle of digital learning objects within a federation of learning object repositories.
