Methodology

The set of properties determined to be the minimum set for interoperability was chosen via discussion at CalConnect’s Roundtables VI and VII and in conference calls of the USECASE Technical Committee. Additional contributions were provided in an informal survey of properties that are built into existing software products that have Task management features, which formed a starting point for further winnowing of properties. The software products were not selected by any formal process, but were those available to which committee participants had access. However, we believe these to be a fair representation of the types of calendaring products currently in use. Eventually the USECASE Technical Committee decided that it was advisable to proceed by accepting those properties which were implemented by more than fifty percent (>50%) of the software surveyed as representing a minimum set for interoperability.

• Oracle Calendar

• Yahoo
