Declarative Constrained Language for Semistructured Data
Mohand-Saïd Hacid, Farouk Toumani · Flexible Query Answering Systems · 2001
In this paper we consider how constraint-based technology can be used to query semistructured data. We present a formalism based on feature logics for querying semistructured data. The formalism is a hybrid one in the sense that it combines clauses with path constraints. The resulting language has a clear declarative and operational semantics. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
