Managing Branch Versioning in Versioned/Temporal XML Documentsred our technique to a timestamped XML solution and a set of Web services has been developed. The easy management of multiple versioning, the large number of queries in different XML standard query languages and its implementation by using only XML technology, are some of the advantages of the proposed technique.

The Generation Y of XML Schema Matching Panel Descriptionh, schema matching has impact on numerous applications. It impacts business, where company data sources continuously realign due to changing markets. It also impacts life sciences, where scientific workflows cross system boundaries more often than not.

Normalization Theory for XMLations, not all are good – some are prone to redundancies and update anomalies. In the relational world we have a well-developed theory of data design (also known as normalization). A few definitions of XML normal forms have been proposed, but the main question is . a particular design is good. In t

XPath Query Satisfiability is in PTIME for Real-World DTDse is some document valid with respect to . on which . returns a nonempty result. Recent studies in the literature have shown the problem to be NP-hard or worse for most fragments of XPath. However, in this paper we show that the satisfiability problem is in PTIME for most DTDs used in real-world app

Efficient XQuery Evaluation of Grouping Conditions with Duplicate Removalsuery language. As users integrate this new construct into their applications, it becomes important to have efficient evaluation techniques available to process even complex grouping conditions. Among them, the removal of distinct values or distinct nodes in the partitions defined by the . clause is

On the Effectiveness of Flexible Querying Heuristics for XML Dataelevant proposals employs heuristics that identify groups of meaningfully related nodes using information extracted from the input data. These heuristics are employed to effectively prune the search space of all possible node combinations and their popularity is evident by the large number of such h

XML Schema Evolution: Incremental Validation and Efficient Document Adaptationuments. XML Schemas, however, may need to be updated to adhere to new requirements and to face changes in the application domain. Starting from a set of schema modification primitives, in this paper we devise an incremental validation approach that allows to efficiently validate documents, known to
