Midgard 1.8alpha2 "Independent" released

New branch provides metadata for all objects registered from schemas. Improved MgdSchema types managament includes features like automatic guid accessibility and ISO datetimes.

Midgard-schema, new command line tool creates database's storage tables and performs tests on registered types before implementing application in production environment.

PHP is no more the only one scripting language supported by Midgard. Due to MgdSchema technology Midgard provides better connectivity for Java developers.

1.8 branch is the last one Midgard branch with repligard. A new Java tool, Exorcist is available as a preview for general database replication, including Midgard and other CMS's databases.

Midgard 1.8 for end users

Unified Configuration

New configuration file format allows users to reuse the same midgard configuration among many different applications and among many environments. New file format is in beta state in this release and will be provided as the only one recommended way to configure any applications in future Midgard releases. The main goal is to reuse configuration even with different binaries without any need to rebuild Midgard.

Installation improvements

• Midgard CMS - MidCOM is installable and available as PEAR packages.
• New command line tool midgard-schema allows developers to create objects' database storage automatically. This tool is also able to perform basic object's operations ( like invoking real create or update methods ) before classes are registered in production environment.

New file format is currently supported by:

• midgard-php used with php-cli
• midgard-schema
• midgard-query
• midgard-apache2 module

Midgard 1.8 for developers

Midgard metadata.

New midgard_metadata class is new Midgard's internally initialized type which is integral part of every user defined class. midgard_metadata object is accessible as 'metadata' property for every newly created object instance. Informations like date of object's creation or last update, visibility or object's creator are available for all classes defined in schema files. This functionality also supports sheduling dates for registered classes. Even for attachments or persons.

Midgard metadata in Query Builder

As Midgard Query Builder is the default way to query objects from database, it also supports metadata constraints. Any object may be queried from database not only using its own properties but also using metadata property.

ISO datetimes

Following Midgard mRFC 0020 midgard_metadata properties with MGD_TYPE_TIMESTAMP represents dates as ISO datetimes. All dates are stored in UTC timezone in database.

Improved support for GUIDs

All midgard_metadata properties which are links to other types use only guids instead of ids. Additionaly every object in midgard database is represented by guid which is now stored in object's table and doesn't have to be retrieved by particular method. Database upgrade performed by datagard updates every record in database, so even records created or updated with old traditional Midgard API are converted and ready for new applications.

Midgard Reflection

Midgard Reflection is designed for developers who need to write "schema aware" applications without any knowledge about schema registered for application.Property's or type's attributes defined in schema files are easily accessible with Midgard Reflection objects.

New datatypes for object's properties.

With Midgard's Reflection one may retrieve property's type. Types like longtext or datetime defined in application's schema are easily accessible on any level wihout any need to redefine such data for application which create user's GUI based on used objects.
