    Krishnaprasad Thirunarayanet al. A coherent query language for XML

    • ...In the context of XML, many attempts to deÞne graphical query languages have been proposed: QSByE (Querying Semi-structured data by Example) [11], XQBE [6], Miro-web [5], EQUIX [9], BBQ [14], Pesto [7], QURSED [15], visXcerpt [3] and Xing [10]...
    • ...Their main limitations are that no semantics is formally assigned to those graphs hence they do not account for correctness proofs of the translation (usually to XQuery) they implement and last, except for [3] they never exploit the underlying type system in order to yield optimized versions of the resulting queries...

    Véronique Benzakenet al. Pattern by example: type-driven visual programming of XML queries

    • ...First, Datalog rules (essentially conjunctive queries) provide an elegant formalization for many query languages (or important parts thereof) for semi-structured data, relational data (or both) such as XPath [13] (and therefore XQuery), XSLT (which can be mapped to a conjunctive query as it can be mapped to SQL [17]), XCerpt [7], SPARQL [27] (also see [8]) and SQL4X [9]...
    • ...XCerpt [7] is a rule-based language for querying semi-structured data with recursion capabilities...
