[Archivesspace_Users_Group] EAD Importer and DAOs

Hi Brian,

I don't think it's a good idea to change the data model just to avoid imports failing, though there may be other rationales that result in such a change.

In the mean time, it might be useful to write some XSLT or some other custom code to perform sanity checks relative to ASpace restrictions ahead of EAD import attempts. In that manner, those non-conformant captions (and anything else you check on) could be tweaked before import.

As part of this process, the @title attribute is used for both the digital object title, and the caption under file versions.  I've recently run into a fun issue with <dao>s with @titles longer than 255 characters.  These titles are OK for digital_object:title, which is VARCHAR(8704) but too long for file_version:caption, which is VARCHAR(255).  So the import fails.

If it is, and if one were theoretically considering a PR, would it make more sense to harmonize the length of the title and caption, or truncate the caption to 255 characters?  My inclination is just to increase the maximum length of captions, and rely on people to show restraint, but I know that other people might have different opinions.
