Is the OBIS Schema compatible with the Darwin Core standard?
Yes. The OBIS schema was built as an extension to the Darwin Core version 2 standard (http://tsadev.speciesanalyst.net/documentation/ow.asp?DarwinCoreV2). [The Darwin Core is a standard that is used by the Global Biodiversity Information Facility and several networks of museum collections] So it contains all of the Darwin Core fields with the same names. The OBIS Schema also contains some additional fields for holding information that the Darwin Core does not handle. So, if you implement the OBIS Schema in your database, you will be compliant with both the Darwin Core standard and the OBIS standard.
