If you have old records in DC (or OLAC, a linguistic extension of DC) you can use the following profile: [OLAC-DcmiTerms](http://catalog.clarin.eu/ds/ComponentRegistry?item=clarin.eu:cr1:p_1288172614026)

From that profile you can generate the XSD: [http://catalog.clarin.eu/ds/ComponentRegistry/rest/registry/profiles/clarin.eu:cr1:p\_1288172614026/xsd](http://catalog.clarin.eu/ds/ComponentRegistry/rest/registry/profiles/clarin.eu:cr1:p_1288172614026/xsd)

And then you can transform your DC XML files into CMDI files that comply with the profile with the following XSLT: [olac-cmdi](https://github.com/clarin-eric/metadata-conversion/tree/master/olac-cmdi)

An example (DC) inputfile: [oai\_ota\_oucs\_0001.xml](http://infra.clarin.eu/cmd/example/conversion/input/oai_ota_oucs_0001.xml)  
The corresponding (CMDI) outputfile: [oai\_ota\_oucs\_0001.cmdi](http://infra.clarin.eu/cmd/example/conversion/output/oai_ota_oucs_0001.cmdi)
