UD_Old_East_Slavic-RNC is a sample of the Middle Russian corpus (1300-1700), a part of the Russian National Corpus. The data were originally annotated according to the RNC and extended UD-Russian morphological schemas and UD 2.4 dependency schema.

The lists of part-of-speech and core grammatical tags is available at: , the document also shows the mapping between the RNC and UD tags.
