Externalizing document management is a problem when individual or corporate privacy is to be ensured. Provided that the decryption key is not known from service side, pure storage/archiving of encrypted documents is highly secure, but of poor interest as no operation can be performed on hosted data. Thus, current document management systems offer restricted privacy mechanisms, roughly based on secured communication channels and sometimes encrypted storage. However, many value-added processing operations require decrypting the document, and no formal guaranty is granted regarding the safety of system behaviors. As an example of known issue, there is the problem of data remanence (persisting information on disk after file system deletion), bugs or viruses acting on various level of the software architecture. This paper describes a method to allow restricted (but yet meaningful) ways of processing encrypted XML documents without needing decryption phase. The encryption process we propose allows isomorphic encryption of data (XML document owned by customers) and operator transformations (verification and transformation operated by the Service Provider) in such a way that full secrecy is ensured simply because the decoding key is not known by the Service Provider. Once transformed, operators can handle encrypted documents with equivalent results up to the decryption operation.

Purpose The purpose of this paper is to demonstrate the value of using a systematic literature review to develop an integrated framework for information and knowledge management systems. Design/methodology/approach First, the systematic literature review method is introduced, differentiating it from traditional literature reviews in terms of value-added and limitations. Second, this methodology is used in a research application focused on absorptive capacity internal capabilities with regard to the processes of acquisition, assimilation, transformation and exploitation. Third, an integrated framework for information and knowledge management systems is developed from this application. Findings The systematic literature review approach provides a rigor that can assist in reducing researcher bias while simultaneously enabling the definition of a precise scope of review, with a clear explanation of selection criteria with the objective to find and review all the studies that are relevant to the search definitions. As a research method, it effectively supports a qualitative, quantitative or mixed methodology. Research limitations/implications This methodology was applied to one specific area of research. Specific limitations include the availability of articles in subscribed databases and the analytical capabilities of the tools used for text mining and analytics. Originality/value This paper demonstrates the usefulness of the systematic literature review methodology in developing an integrated framework for analysis.

XML (Extensible Markup Language) represents one of flexible platforms for processing enterprise documents. Its simple syntax and powerful software infrastructure for processing this type of documents is a guarantee for high interoperability of individual documents. XML is today one of technologies influencing all aspects of ICT area.In the paper questions and basic principles of reusing XML-based documents are described in the field of enterprise documents. If we use XML databases or XML data types for storing these types of documents then partial redundancy could be expected due to possible documents’ similarity. This similarity can be found especially in documents’ structure and also in documents’ content and its elimination is necessary part of data optimization.The main idea of the paper is focused to possibilities how to think about dividing complex XML docu­ments into independent fragments that can be used as standalone documents and how to process them.Conclusions could be applied within software tools working with XML-based structured data and documents as document management systems or content management systems.

Introduction: In rural developing countries with a traditional manure management, animal manure is a value-added agricultural commodity being utilized as a source of fuel and plant nutrients. The sustainable environmental management of this resource has to consider the whole upstream and downstream activities of current management systems. Methods & Materials: In line with this requirement, this study has integrated the Intergovernmental Panel on Climate Change (IPCC) method on manure managements into the life-cycle assessment of two different manure management systems: the traditional system without biogas production and the alternative system with biogas production. Special attention is given to compare the GHG emissions as well as Nitrogen (N), Phosphorous (P), and Potassium (K) Fertilizing Nutrients (NPK) from the two systems. Results: The great advantage of manure conversion to biogas is mainly due to the avoided wood (18 kg/animal.yr), crop-residues (12 kg/ animal.yr) and dung (8 kg/ animal.yr) used as cooking fuels in the region. If methane leakage is over 38% then this will offset the GHG emission reduction of manure-to-biogas system.

Designing a well-structured XML document is important for the sake of readability, maintainability and more importantly to avoid both data redundancies and update anomalies. This paper proposes to improve and simplify XML structural design using a normalization process. To achieve this, Graphical Notation for Document Type Definition (GN-DTD) is used to describe the structure of XML document at the schema level. Multiple levels of normal forms for GN-DTD are proposed and the corresponding normalization rules to transform from poorly designed into well-designed XML documents. A case study is presented to show the application of these normal forms and normalization algorithm.

Classification/clustering of XML documents based on their structural information is important for many tasks related with document management. In this chapter, we present a suite of algorithms to compute the cost for approximate matching between XML documents and schemas. A framework for classifying/clustering XML documents by structure is then presented based on the computation of distances between XML documents and schemas. The backbone of the framework is the feature representation using a vector of the distances. Experimental studies were conducted on various XML data sets, suggesting the efficiency and effectiveness of our approach as a solution for structural classification/clustering of XML documents.

Content management is essential for organizational work. It has been defined as “a variety of tools and methods that are used together to collect, process, and deliver content of diverse types” (McIntosh, 2000, p. 1). Content management originates from document management. In fact, a great deal of contemporary content management system functionality has evolved from document management systems. Documents are identifiable units of content, flexibly structured for human comprehension (Murphy, 2001; Salminen, 2003). They have traditionally been considered as containers for organizational content. Document management considers the creation, manipulation, use, publishing, archiving, and disposal of documents as well as the continuous development and design of these activities in organizational domains. In different domains, the requirements for document management differ accordingly. For example, manufacturing companies possess a bulk of technical drawings to be managed, and in e-government organizations, the document content may act as a normative reference that needs to be frozen and archived for long periods of time (Honkaranta, Salminen, & Peltola, 2005). Therefore document management in e-government is commonly split into two types: document management focusing on document production and the records management considering document repository management. Research on document management in organizations has been carried out focusing on a multitude of issues, including document standardization (Salminen, 2003), document metadata (Murphy, 1998), document and information retrieval (Blair, 2002), the social role of documents for organizational groups (Murphy, 2001), as well as document engineering (Glushko & McGrath, 2005). The wide selection of content management systems available has evolved mainly from document management systems (Medina, Meyers, Bragg, & Klima, 2002). They combine into single systems various functionalities developed separately in domains such as library sciences, text databases, information retrieval, and engineering databases. The essential features of document management systems cover: • Library services and version management • Management of user roles and access rights • Text retrieval based on metadata and full-text search • Support for document life-cycle and related work- flows • Management of metadata, as information about documents • Multi-channel publishing for a multitude of devices and print A survey on content management systems revealed that many of the systems still have a monolithic and closed architecture and their ability to adopt proprietary encodings is scarce (Paganelli & Pettenati, 2005). Contemporary content management systems’ support for access management and for customizing workflows for integrating content into organizational processes may be modest. For example, the popular Microsoft SharePoint Server (http://www.microsoft. com/sharepoint/default.mspx) only assigns access rights to folders, not to individual files or units within the files. Content management software may include limited functionality for the design and management of an organization’s Web site. The applicability of the document management approach and the systems for content management have been limited due to an orientation towards using documents as the only unit for managing content. As a consequence of this approach, long documents are difficult to browse through, portions of document content are difficult to reuse in other documents, and long documents are inconvenient for Web delivery (Honkaranta et al., 2005). At least two recent approaches on content management which aim at complementing these weaknesses can be identified. These are Web content management and the use of structured documents in the form of XML.
