Microsoft unveiled the building blocks of their “OSLO” vision during the PDC event in Los Angeles in October. As the article explains
Oslo has three main components:
- A modeling language M for textual DSLs
- Quadrant a design surface for graphical DSLs
- A relational database repository that stores these models.
The textual language development consists of is a three core languages, technically two that any given developer can author in:
- MGrammar: defines grammars for Syntax Directed Translation.
- MSchema: Is a language that defines schemas for a Semantic Model, that, model-aware runtimes can use.
- MGraph: represents an object graph of a translation of a given textual input against a parser defined using MGrammar.
This article is an attempt to try and use the MGrammar language to write our own language, a DSL, for expressing dates in natural language using the OSLO tool chain.
