Glossary

This glossary is for developers. A computer-science degree isn't required, but it will help.

term	meaning
document	A bunch of text (characters that can be represented in XML 1.0 and XML 1.1). Every document has metadata, both for its intrinsic value and to help Overview display it.
document set	A collection of documents that the user chooses to analyze together. Equivalent to a "project" in other programs. Each document set is mostly self-contained: documents, tags, searches, trees and vizs cannot span multiple document sets.
file	Binary data a user uploads. A file may be used by many documents in many document sets.
tag	A small text string, selected by the user, that applies to a group of documents (selected by the user).
search	A small text string, selected by the user, that finds a group of documents (selected by their text).
tree	A hierarchical clustering of documents in a document set.
node	One entry in the tree. The root node is the top of the tree. Each node holds a set of documents, and most nodes have child nodes. All of the documents in the child nodes are, collectively, the documents in the parent node.
viz	A way of grouping and displaying documents for the user. It's an abstract idea; the tree is a concrete implementation.
