The Vedic Treebank is a new treebank of Vedic Sanskrit annotated according to the Universal Dependencies standard, with minor revisions. It contains selected passages from 37 texts belonging to the Vedic literature, covering both metrical and prose texts and spanning from the R̥gveda to the early Upaniṣads.

The Vedic Treebank is a valuable tool for historical linguists, computational linguists, philologists, and Sanskrit scholars.
The current version can be downloaded from the GitHub repository in CoNLL-U format. It can be queried with processing and visualization tools provided by Universal Dependencies, such as Tred, Udapi, and CoNLL-U viewer.

The Vedic Treebank was also converted into Universal Dependencies. In this version, it can be queried online with the PML Tree Query Engine (link:!/home).
