On some technological issues of LuNA active knowledge system implementation

Active knowledge concept is a methodology for parallel programs con- struction automation. It allows automatic construction of programs which meet non-functional requirements in particular subject domains. To support the automa- tion an active knowledge base has to be constructed, which contains information on peculiarities of the subject domain. LuNA system is an academic project aimed at implementation and practical research of the active knowledge concept. In the paper we concern some technological problems which arise during practical imple- mentation of the active knowledge concept, as well as their solutions developed in LuNA project.
