Treex-PML This module implements a basic API for working with Prague Markup Language (PML). Prague Marup Language (PML) is an XML-based, universally applicable data format based on abstract data types intended primarily for interchange of linguistic annotations. It is completely independent of a particular annotation schema. It can capture simple linear annotations as well as annotations with one or more richly structured interconnected annotation layers, dependency or constituency trees. A concrete PML-based format for a specific annotation is defined by describing the data layout and XML vocabulary in a special file called PML Schema and referring to this schema file from individual data files (instances). The schema can be used to validate the instances. It is also used by applications to ``understand'' the structure of the data and to choose optimal in-memory representation. The generic nature of PML makes it very easy to convert data from other formats to PML without loss of information. PML and was developed at the Institute of Formal and Applied Linguistics of the Charles University in Prague. It was first used in the Prague Dependency Treebank 2.0 and several other treebanks since. Conversion tools for various existing treebank formats are available, too. See http://ufal.mff.cuni.cz/jazz/pml/ Note: this library was originally developed for the TrEd framework (http://ufal.mff.cuni.cz/~pajas/tred) and evolved gradually from an older library called Fslib implementing a different data format.
