Currently the trend in digital publishing of Humanities data seems to be movingtowards openness and interoperability [1]. In this abstract I will examine to what extentand in what way current digital publications are open and accessible. My hypothesis isthat while many digital publications are currently made available online and can besearched and viewed by the general public, very few are available to researchers in ameaningful way. By meaningful I mean that external researchers can search and exportdata for reuse and are possibly even encouraged to define their own search criteria. Ibelieve that this is the true essence of data sharing [2].Following this, I will propose one approach, using XML and Web Services, tocreating a digital publication of Humanities data that would be open to the researchcommunity in a meaningful way, as defined above.
