GZP - a secure and compressed package of Guru objects and their attributes. Guru objects can be anything used by the Cassini ATE platform such as: calibration data, test programs, device definitions (drivers), diagnostic data, security or configuration files. These files are used to transport Guru objects as files via email, FTP or any other traditional method.



Import Preview Color Coded .GABs:
Green text denotes objects that do not currently exist in the local Guru and will imported
Red text denotes that object to be imported is newer than the version that exists on the local Guru. This object will be imported, and when requested by an application, the imported version will be used. The older version will be saved in the local guru’s revision history.
Magenta text denotes that object to be imported is older than the version that exists on the local Guru. This object will be imported, and when the object resource is requested by an application, the current version on the local Guru will be used. The imported older version will be saved in local guru’s revision history.
Black text denotes that the object already exist in the local Guru and is the most current version and as such, the object in the import list will not be imported.

What is in a GZP?
A file with .GZP extension is a compressed "Guru" package of files that contains Guru Objects and their attributes (stored internally as ".GAB" and ".GOB" pairs), very similar and compatible with ZIP files but is NOT just any .ZIP or .GZIP (GnuZIP) file. Since Guru objects can never be changed (they are immutable), importing a .GZP file will only add Guru Objects that are not already there. Using Guru Browser, Guru Explorer, or Guru Import Utility to import .GZP files will not duplicate identical guru objects, if the exact object already exists, it will not be imported when using "import" from Guru Browser.

.GAB - Guru AttriBute file - ASCII "CFF" representation of the key-value pairs that IS the Guru Attributes

.GOB - Guru OBject file - Binary or ASCII (CFF) representation of the object itself. For example, a JPEG image file can be read by any image viewer.
Tip! Cal data can be viewed and exported to .csv with the
RI Cal Export app.

Manifests
A manifest is a collection of links to other Guru Objects that are active or otherwise required to be included. For example, a RiTestSessionDef will include a link to the RiTestplan (CID for specific version, RevisionID for the latest) and the RiTestplan will have a manifest with links to the Device Control definition and any other transient "instruments" active while saving. Another example is a RiPatch with device firmware or dependancies.

Security
The objects in a .GZP file is digitally signed, so you can NOT modify a .GZP to include other GABs and GOBs or make changes to the contents of either file. Only the original objects that pass signature verification will be imported. This also identifies and prevents file corruptions (typically introduced when using FTP in ASCII mode) from being imported into Guru. Any needed RiCert object is included to be able to validate the digital signature when importing.

Viewing with standard applications
You can append or rename a .GZP file with .ZIP and use any application that can read "ZIP" files to decompress the file and see the attributes and objects contained in it. May contain permission certificates used to authenticate the digital signatures. May contain a list of objects in human readable format in a log file. May contain "manifest" file of related objects that were included because they are used together. As noted above, any additions to the .GZP file will not be processed due to the security of the import process.
