Hi Katherine,
Your project is ambitious. And in many ways it needs to be in order to address the “long-standing problem in historic cemeteries studies” you have identified — providing a unified way to access an abundance of dispersed funerary monument records.
While the overarching goal of the project is clearly valuable and would positively impact the audiences you have identified (academics, professionals, genealogists, etc.), I think you should focus your attention on one or possibly two of the outcomes in your vision document. Otherwise you will not have enough time to deliver a polished final product for the summer institute.
I just finished finalizing the metadata schemas for ARCS. It took the team and me around 12 months to do this. Right now a colleague of mine is scrubbing ARCS data (from a pilot database created 2 years ago) for upload into KORA w/ the new schema. It is time-consuming work even with OpenRefine. In short, it took much longer than I imaged to lay the foundation for the ARCS repository. Therefore unless you have the MAP system already in place, I expect it will be a significant time suck for you to do the same.
Depending on how you want narrow your project, I can envision you developing detailed work plans for carrying out other phases of MAP. In this way, you could simultaneously complete one component of the larger MAP project for the summer institute while sketching out your plans for completing other components later on. The planning materials for the future components might include testing and evaluating tools you would use for the map or the crowdsourcing, etc.
