In order for a digital project to really live up to its potential–the possibilities it has over print–it has to include an infrastructure. We have already been working on creating structured data, but now we have to think about building a repository for that data. As long as data is confined to a particular space–be it a book, laptop or even cloud service–it is accessible only through the entry points that medium makes available.
Many formats make it easy to access information, but difficult to put that information into relationship with other information. What is more, that information is largely from a single source (an author) and cannot be changed or updated as new information comes available, nor can it be altered by anyone other than the author.
That is the power of digital projects: by building an online architecture for your data, you make ongoing collaboration and community-sourced data possible.
