Content Management System

20 Feb

Progress on DivConq Framework 0.5 is still being made. We are currently building a CMS on the DivConq Framework which is needed by one of our partner projects. The CMS will also be open source and available for download at this site. Building an application using DivConq also helps serve as a sanity check for the Framework design, so although it may slow progress a little it will help mature the Framework.

Date Time Plans

06 Feb

Neither the MUMPS standard, nor the GT.M implementation, come with much date time support. Even if it did it would differ from Java’s support and from the various Javascript libraries out there. For DivConq we want to provide consistent date time formatting and parsing for MUMPS (your stored procedures and queries), for Java (your business logic and EDI) and for Javascript (your web UI). Further, as already mentioned elsewhere, we support the BigDateTime data type for dates from -50 billion to +50 billion years.

Our date time formatting support starts within MUMPS. Recent releases of DivConq have considerable support for querying the database, but date time is always returned in the internal format (ISO 8601) or in the internal BigDateTime format – and also always store times using the UTC timezone. In DivConq every request to the database silently carries the current task’s (user’s) timezone (chronology) and locale. Therefore we have the info we need format a date time within MUMPS. Our current work is to code support for chronologies and timezones.
