SISO-STD-014.1-2018 “Gateway Description Language” and SISO-STD-014.2-2018 “Gateway Filtering Language” compose a family of specifications, one each for two different eXtensible Markup Language (XML)-based formal languages, used by both developers and users of Live, Virtual, and Constructive (LVC) environments during gateway selection and configuration. Each specification reflects a different aspect of the overarching process of gateway selection and configuration.

The description of these languages is as follows:

Gateway Description Language (GDL): A common human-readable and machine-readable format/syntax for describing both user gateway requirements and the capabilities that individual gateways can offer to users. GDL also includes gateway performance information.

Gateway Filtering Language (GFL): A common human-readable and machine-readable format/syntax for capturing the traffic filtering details of a gateway.

The GDACL Product Support Group (PSG) purpose is to provide support for users of GDL and GFL, including a discussion board and help for any issues using these standards.

The GDACL PSG is also the place to submit problem and change requests (PCRs) which is the approved method of getting changes or new additions into the future revision of the standards.
