Conception and Implementation of a Functional Querying- and Transformation-API

所请求的研究项目的目标是根据嵌入在基于JVM的函数式编程语言Clojure中的函数式API，构思并实现一种灵活且可扩展的模型查询和转换方法。该方法将涵盖经典的转换用例，即生成性(异地)转换以及修改(就地)转换。此外，主要研究工作的一点将花在元模型及其模型实例的共同进化领域。在这里，转换不会将符合某些固定元模型的输入模型迁移到符合某些固定输出元模型的新模型，而是在原地修改包含一致性模型的元模型。最初，该方法将使用申请人的TGRAPH技术实现，但它也将扩展到其他技术空间，以便允许跨越技术空间的边界进行转换。因此，也将关注不包含在ModelWare综合体中的技术空间。

The goal of the requested research project is the conception and realization of a flexible and extensible approach for model querying and transformation in terms of a functional API embedded in the JVM-based, functional programming language Clojure.The approach will cover both classical transformation use-cases , namely generative (out-place) transformations as well as modifying (in-place) transformations. Furthermore, one point of main research effort will be spent in the fields of co-evolution of metamodels and their model instances. Here, transformations don't migrate input models conforming to some fixed metamodel to new models conforming to some fixed output metamodel, but instead transformations modify metamodels incuding conforming models in-place.Initially, the approach will be realized using the applicant's TGraph technology, but it will be extended to other technological spaces as well in order to allow for transformations crossing the borders of technological spaces. Hereby, attention will also be paid to technological spaces which are not contained in the ModelWare complex.
