While most systems intend to deliver a paperless environment to each institution it is recurrent that document integrity and accountability is still relying on traditional methods such as producing physical documents for signing and archiving. While this method delivers a non-efficient work- flow and has an effective monetary cost, it is still the common method to provide a degree of integrity and accountability on the data contained in the databases of the information systems. The evaluation of a document signature is not a straight forward process, it requires the recipient to have a copy of the signers signature for comparison and training beyond the scope of any office employee training, this leads to a serious compromise on the trustability of each document integrity and makes the verification based entirely on the trust of information origin which is not enough to provide non-repudiation to the institutions. -
XML Signature/Encryption — the Basis of Web Services Security
Special Issue on Security for Network Society Falsification Prevention and Protection Technologies and Products XML Signature/Encryption — the Basis of Web Services Security By Koji MIYAUCHI* XML is spreading quickly as a format for electronic documents and messages. As a consequence, ABSTRACT greater importance is being placed on the XML security technology. Against this background research and development efforts into XML security are being energetically pursued. This paper discusses the W3C XML Signature and XML Encryption specifications, which represent the fundamental technology of XML security, as well as other related technologies originally developed by NEC. KEYWORDS XML security, XML signature, XML encryption, Distributed signature, Web services security 1. INTRODUCTION 2.

Extensible Markup Language (XML) and Its Role in Supporting the Global Justice XML Data Model
Extensible Markup Language (XML) and Its Role in Supporting the Global Justice XML Data Model Extensible Markup Language, or "XML," is a computer programming language designed to transmit both data and the meaning of the data. XML accomplishes this by being a markup language, a mechanism that identifies different structures within a document. Structured information contains both content (such as words, pictures, or video) and an indication of what role content plays, or its meaning. XML identifies different structures by assigning data "tags" to define both the name of a data element and the format of the data within that element. Elements are combined to form objects. An XML specification defines a standard way to add markup language to documents, identifying the embedded structures in a consistent way. By applying a consistent identification structure, data can be shared between different systems, up and down the levels of agencies, across the nation, and around the world, with the ease of using the Internet. In other words, XML lays the technological foundation that supports interoperability. XML also allows structured relationships to be defined. The ability to represent objects and their relationships is key to creating a fully beneficial justice information sharing tool. A simple example can be used to illustrate this point: A "person" object may contain elements like physical descriptors (e.g., eye and hair color, height, weight), biometric data (e.g., DNA, fingerprints), and social descriptors (e.g., marital status, occupation). A "vehicle" object would also contain many elements (such as description, registration, and/or lien-holder). The relationship between these two objects—person and vehicle— presents an interesting challenge that XML can address. -
Odfweave Manual
The OdfWeave Package Max Kuhn max.kuhn@pfizer.com August 7, 2007 1 Introduction The Sweave function (Leisch, 2002) is a powerful component of R. It can be used to combine R code with LATEX so that the output of the code is embedded in the processed document. The capabilities of Sweave were later extended to HTML format in the R2HTML package. A written record of an analysis can be created using Sweave, but additional annotation of the results may be needed such as context–specific interpretation of the results. Sweave can be used to automatically create reports, but it can be difficult for researchers to add their subject–specific insight to pdf or HTML files. The odfWeave package was created so that the functionality of Sweave can used to generate documents that the end–user can easily edit. The markup language used is the Open Document Format (ODF), which is an open, non– proprietary format that encompasses text documents, presentations and spreadsheets. Version 1.0 of the specification was finalized in May of 2005 (OASIS, 2005). One year later, the format was approved for release as an ISO and IEC International Standard. There are several editors/office suites that can produce ODF files. OpenOffice is a free, open source editor that, as of version 2.0, uses ODF as the default format. odfWeave has been tested with OpenOffice to produce text documents. As of the current version, odfWeave processing of presentations and spreadsheets should be considered to be experimental (but should be supported in subsequent versions). OpenOffice can be used to export the document to MS Word, rich text format, HTML, plain text or pdf formats. -
Extensible Markup Language (XML)
15 Extensible Markup Language (XML) Objectives • To mark up data, using XML. • To understand the concept of an XML namespace. • To understand the relationship between DTDs, Schemas and XML. • To create Schemas. • To create and use simple XSLT documents. • To transform XML documents into XHTML, using class XslTransform. • To become familiar with BizTalk™. Knowing trees, I understand the meaning of patience. Knowing grass, I can appreciate persistence. Hal Borland Like everything metaphysical, the harmony between thought and reality is to be found in the grammar of the language. Ludwig Wittgenstein I played with an idea and grew willful, tossed it into the air; transformed it; let it escape and recaptured it; made it iridescent with fancy, and winged it with paradox. Oscar Wilde Chapter 15 Extensible Markup Language (XML) 657 Outline 15.1 Introduction 15.2 XML Documents 15.3 XML Namespaces 15.4 Document Object Model (DOM) 15.5 Document Type Definitions (DTDs), Schemas and Validation 15.5.1 Document Type Definitions 15.5.2 Microsoft XML Schemas 15.5.3 W3C XML Schema 15.5.4 Schema Validation in C# 15.6 Extensible Stylesheet Language and XslTransform 15.7 Microsoft BizTalk™ 15.8 Summary 15.9 Internet and World Wide Web Resources 15.1 Introduction The Extensible Markup Language (XML) was developed in 1996 by the World Wide Web Consortium’s (W3C’s) XML Working Group. XML is a portable, widely supported, open technology (i.e., non-proprietary technology) for describing data. XML is becoming the standard for storing data that is exchanged between applications. Using XML, document authors can describe any type of data, including mathematical formulas, software-configu- ration instructions, music, recipes and financial reports. -

W3C liability, trademark and document use rules apply. Abstract The current Web is primarily made up of an enormous number of documents that have been created using HTML. These documents contain significant amounts of structured data, which is largely unavailable to tools and applications. When publishers can express this data more completely, and when tools can read it, a new world of user functionality becomes available, letting users transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience: an event on a web page can be directly imported - 1 - How to Read this Document RDFa in XHTML: Syntax and Processing into a user’s desktop calendar; a license on a document can be detected so that users can be informed of their rights automatically; a photo’s creator, camera setting information, resolution, location and topic can be published as easily as the original photo itself, enabling structured search and sharing. -

Page 1 of 12 Digital Preservation Assessment: Date: 20/09/2016 Preservation Open Document Text (ODT) Format Team Preservation Assessment Version: 1.0 1. Introduction This document provides a high-level, non-collection specific assessment of the OpenDocument Text (ODT) file format with regard to preservation risks and the practicalities of preserving data in this format. The OpenDocument Format is based on the Extensible Markup Language (XML), so this assessment should be read in conjunction with the British Library’s generic format assessment of XML [1]. This assessment is one of a series of format reviews carried out by the British Library’s Digital Preservation Team. Some parts of this review have been based on format assessments undertaken by Paul Wheatley for Harvard University Library. An explanation of the criteria used in this assessment is provided in italics below each heading. [Text in italic font is taken (or adapted) from the Harvard University Library assessment] 1.1 Scope This document will primarily focus on the version of OpenDocument Text defined in OpenDocument Format (ODF) version 1.2, which was approved as ISO/IEC 26300-1:2015 by ISO/IEC JTC1/SC34 in June 2015 [2]. Note that this assessment considers format issues only, and does not explore other factors essential to a preservation planning exercise, such as collection specific characteristics, that should always be considered before implementing preservation actions. -

Chapter 13 XML: Extensible Markup Language
Chapter 13 XML: Extensible Markup Language - Internet applications provide Web interfaces to databases (data sources) - Three-tier architecture Client | V Application Programs Webserver | V Database Server -HTML common language for Web pages-not suitable for structure data extracted from DB - XML is used to represent structured data and exchange data on the Web for self-describing documents - HTML, static Web pages; when they describe database data, they are called dynamic Web pages 1. Structured, Semi-structured and Unstructured data -Information in databases is a structured data (employee, company, etc), the database checks to ensure that all data follows the structure and constraints specified in the schema 1 - some attributes may be shared among various entities, other attributes may exist only in few entities Semi-structured data; additional attributes can be introduced later Self-describing data as schema can change Example: Collect a list of biographical references related to a certain research project - Books - Technical reports - Research articles in Journals or Conferences Each have different attributes and information; one reference has all information, others have partial; some references may occur in the future Web, tutorials, etc.. Semi-structured data can be represented using a directed graph. 2 3 Two main differences between semi-structured and object model: 1. Schema intermixed with objects 2. No requirements for a predefined schema Unstructured Data: Limited indication of type of data Example: text document; information is embedded in it 4 HTML document has tags, which specify how to display a document, they also specify structure of a document. HTML uses large number of predefined tags: - Document header - Body - Heading levels - Table - Attributes (tags have attributes) (static and dynamic html) XML Hierarchical Data Model (Tree) The basic object is the XML document. -

DESCRIPTORS *Access to Information; Computer Oriented Programs; *Electronic Libraries; *Information Retrieval; Library Automation; Online Catalogs; *Preservation; Standards IDENTIFIERS Digital Technology; *SGML ABSTRACT This report explores the suitability of Standard Generalized Markup Language (SGML) as a framework for building, managing, and providing access to digital libraries, with special emphasis on preservation and access issues. SGML is an international standard (ISO 8879) designed to promote text interchange. It is used to define markup languages, which can then encode the logical structure and content of any so-defined document. The connection between SGML and the traditional concerns of preservation and access may not be immediately apparent, but the use of descriptive markup tools such as SGML is crucial to the quality and long-term accessibility of digitized materials. Beginning with a general exploration of digital formats for preservation and access, the report provides a staged technical tutorial on the features and uses of SGML. The tutorial covers SGML and related standards, SGML Document Type Definitions in current use, and related projects now under development. A tiered metadata model is described that could incorporate SGML along with other standards to facilitate discovery and retrieval of digital documents.
