EXist and xquery
After an extensive evaluation of the available XML storage solutions eXist was selected as the storage solution for the reBiND project.
Further information about eXist-db and how it benefits the reBiND Project can be found in the article Choosing eXist-db as the XML database for the reBiND project.
The Jetty Web Server is included in the distribution of eXist. It already offers a simple web interface to access the data, an admin backend to manage the files and other useful tools which could become useful for the reBiND Framework.
When looking at the files stored in eXist an hierarchical structure can be seen, comparable to a regular file system. Within eXist Collections are the equivalent to folders in the file system. The root collection is /db/ but usually this can be omitted, so /db/my_collection/data.xml is equivalent to /my_collection/data.xml. XML files stored in eXist are usually called Documents, since the more generic term Files also includes non-XML files, such as text files, images or binary files, which can also be uploaded into eXist. The only file type that cannot be uploaded are non-well-formed XML files.
