# @dh-tools/pdsc Original Author: Marius Seritan This package is used to translate backend models, which are currently written in PDL (you can find out more about PDL as part of LinkedIn's open source rest.li framework at [https://linkedin.github.io/rest.li/pdl_schema](https://linkedin.github.io/rest.li/pdl_schema) ) and translated to PDSC, an older schema spec for rest.li, documented at [https://linkedin.github.io/rest.li/pdsc_syntax](https://linkedin.github.io/rest.li/pdsc_syntax). The PDSC defines the models on the backend, which then are translated to Java classes that get returned in our APIs. Thus, the translation of these models to TypeScript gives us a reliable method to create a JavaScript readable equivalent definition for the API response.
