metaPSL® is a backroom toolkit. It is likely it will never be generally available. It is used to create system description languages, such as PSL and PSL-lite. It is one of the few meta-meta-modelling tools in existence. Its use requires a well-trained and experienced Language Definer. It can only be acquired in conjunction with appropriate consulting and training. Experience has shown that this is the only was it should be made available

metaPSL is a meta-meta-modelling tool. It is used to create meta-modeling tools such as PSL and PSL-lite. Meta-modelling tools such as PSL and PSL-lite are used to create models of systems. Then those models of systems are used by system builders to create working systems. The final piece of the modelling jigsaw is the wisdom needed to make effective use of a meta-meta-modelling tool. Ultimately that can only be derived from human values that identify what is wanted.

metaPSL is based on substantial research spanning philosophy and system description, with the concept of object, property, relationship modelling at its core. Its origins are the same origins as virtually all the well-known modelling techniques (certainly well-known in the information system modelling field) including entity, attribute, and relationship (ERA) modelling, process modelling, object oriented modelling, and so forth.

metaPSL can be made available to organizations that have specific language creation and modelling needs. The modeling techniques behind metaPSL have been used to create languages for business process analysis, IBM's BSP, information achitecture, competence modelling, and PSL.
