+For indexing [CHAT transcription format](http://talkbank.org/manuals/CHAT.pdf) resources converted to [XML](http://talkbank.org/software/xsddoc/), the *mtas.analysis.parser.MtasChatParser* extending the abstract *MtasXMLParser* is available; full examples of configuration files are provided on [GitHub](https://github.com/meertensinstituut/mtas/tree/master/conf/parser/mtas).

+  <mappings>

+  <!-- END MAPPINGS --->
+  ...

+<!-- END CONFIGURATION MTAS PARSER -->
+```

+The syntax of the parser part in the [configuration file](indexing_configuration.html#configuration) is, besides from the *name* attribute, almost identical to the configuration of the [FoLiA-parser](indexing_formats_folia.html) and [TEI-parser](indexing_formats_tei.html).
