    32483266<Text id="oaiserver-22">Greenstone's OAI at present supports 3 metadata formats, as is explained in the instructive comments in the oai.cfg file. Of these three, the OAI standard for Dublin Core, <AutoText text="oai_dc" type="italics"/>, is the one pertinent to this tutorial. If your collection specifies metadata for a different metadata set format, you can use the oai.cfg file to tell Greenstone how to map the metadata fields of your chosen metadata set format into the Dublin Core metadata set supported by the Greenstone OAI server (or one of the other metadata sets it supports).</Text>
    32493267<Text id="oaiserver-23">Look in the oai.cfg file again and scroll down to the section on <Format>oaimapping</Format>, which will explain and provide examples for how to specify such mappings from your metadata format to one that Greenstone's OAI server uses. For instance, the <b>demo</b> collection comes enabled for OAI upon installation, and specifies some mappings from its <AutoText text="DLS" type="italics"/> metadata format to <AutoText text="OAI DC" type="italics"/>. Its <AutoText key="metadata::dls.Title"/> metadata is mapped to <AutoText text="oai_dc.title"/> using the following line in the oai.cfg configuration file (note the use of case):</Text>
