XML semantic constraint validation for XML updates: A survey

2011 International Conference on Semantic Technology and Information Retrieval, 2011
XML databases are commonly used for representing data with more complex structures than traditional relational data. Like in any data model, it is very important to ensure that the contents of the database always valid even after any attempt of updates.

Incremental validation of XML documents

ACM Transactions on Database Systems, 2004
We investigate the incremental validation of XML documents with respect to DTDs, specialized DTDs, and XML Schemas, under updates consisting of element tag renamings, insertions, and deletions. DTDs are modeled as extended context-free grammars. "Specialized DTDs" allow the decoupling of element types from element tags.

XML Validation for Context-Free Grammars

Asian Symposium on Programming Languages and Systems, 2006
String expression analysis conservatively approximates the possible string values generated by a program. We consider the validation of a context-free grammar obtained by the analysis against XML schemas and develop two algorithms for deciding inclusion L(G1)⊆L(G2) where G1 is a context-free grammar and G2 is either an XML-grammar or a regular hedge ...

Single Transition Constraint for XML Update Validation

2012 15th International Conference on Network-Based Information Systems, 2012
In this paper, we propose a checking algorithm for dynamic constraint validation during XML updates. Our algorithm is targeted at single transition constraint, which is affected by single node updating. To the best of our knowledge, almost all constraints that have been preserved in the previous XML updates works are for static constraints.

Incremental Validation of XML Document Based on Simplified XML Element Sequence Pattern

2010 Seventh Web Information Systems and Applications Conference, 2010
With XML becoming the de facto standard for representing and exchanging data on the Internet, the problem of validation of XML data when updated has attracted more and more attentions. The traditional brute-force validation processes the entire updated XML document from scratch, which is less efficient.
