It may look intimidating, but it’s rather simple – an XML input file (actually coming from our old DC4 product here) is formatted as DC-X XML using XSLT. dcx_import.php creates a DC-X document record from that XML (it copies the files referenced in the XML and inserts the metadata into the DC-X database). The dcx_export.php call then runs code against the DC-X PHP API to create a job in the DC-X workflow engine for (re-)creating preview images (you can do this if there are no preview images, or – like in this case – they are too small).

This invocation performs a fulltext search for all documents which have the field “IPTC02015″ set, feeds the document IDs into a script that exports these documents as XML, runs “sed” to change the field name, and uses the modified XML to update the document in the DC-X database. (The fulltext index is automatically updated.) Marvellous!
