| Abstract | When a group of authors collaboratively edits interrelated documents, consistency problems occur almost immediately. Current document management systems (DMS) provide useful mechanisms such as document locking and version control, but often lack consistency management facilities.If at all, consistency is "defined" via informal guidelines, which do not support automatic consistency checks.In this paper, we propose to use explicit formal consistency rules for heterogeneous repositories that are managed by traditional DMS. Rules are formalized in a variant of first-order temporal logic. Functions and predicates, implemented in a full programming language, provide complex (even higher-order) functionality. A static type system supports rule formalization, where types also define (formal) document models. In the presence of types, the challenge is to smoothly combine a first-order logic with a useful type system including subtyping. In implementing a tolerant view of consistency, we do not expect that repositories satisfy consistency rules. Instead, a novel semantics precisely pinpoints inconsistent document parts and indicates when, where, and why a repository is inconsistent.Our major contributions are (1) the use of explicit formal rules giving a precise (and still comprehensible) notion of consistency, (2) a static type system securing the formalization process, (3) a novel semantics pinpointing inconsistent document (parts) precisely, and (4) a design of how to automatically check consistency for document engineering projects that use existing DMS. We have implemented a prototype of a consistency checker. Applied to real world content, it shows that our contributions can significantly improve consistency in document engineering processes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
