Hi there, I am working on a profile of Darwin Core for a metadata repository, and am trying to add mandatory elements to the location class. However, because it is a Dublin Core class, the Darwin Core xsd points me to a file titled "dublin_core.xsd". I cannot seem to find this file, despite digging through what I can find of available Dublin Core xsd files. Although I'm not the most technical, I also believe this will be necessary for adding these changes to our repository (based on GeoNetwork). I was wondering whether someone could send this file to me or otherwise point me in the correct direction? Thanks very much, Kim Mortimer [MERIDIAN on blue circle containing many numbers, with an orange wave pulse to the right.] Kim Mortimer Data Manager MERIDIAN - Marine Environmental Research Infrastructure for Data Integration and Application Network Institute for Big Data Analytics, Faculty of Computer Sciences, Dalhousie University p: + 1 902 494 1812 m: +1 902 880 1863 a: 6050 University Ave, Halifax, NS, B3H 4R2, Canada w: https://meridian.cs.dal.ca e: k.mortimer@dal.ca<mailto:k.mortimer@dal.ca>
