Extensible Markup Language (XML) is a standard format for storing and exchanging data. It allows creation of custom tags to represent information in a structured manner. XML has advantages like domain-specific vocabularies, enabling data interchange between different systems, and performing smart searches. The key components of an XML document include tags, elements, attributes, and content to represent hierarchical relationships between various data entities.

SOAs improve robustness by leveraging web standards and allow easier evolution of applications since services have well-defined interfaces and exchange self-describing messages rather than being tightly coupled. This represents a significant evolution from traditional distributed programming models.
ModelTalk - When Everything is a Domain Specific LanguageAtzmon Hen-Tov
- ModelTalk is a model-driven software development framework that supports domain-specific languages (DSLs) pervasively at the core of the development process.
- In ModelTalk, systems are implemented primarily using declarative DSL code, with some localized Java code for behavior. The DSL code governs the Java code.
- ModelTalk uses three principles for DSL development at scale: textual DSLs, an integrated IDE for DSL and Java development, and an interpretive approach where DSL code does not need to be transformed to Java.

This document provides an overview of XML basics, including what XML is, its advantages over HTML, related technologies like DTDs and XML schemas, how XML can be used, XML tags and syntax rules, and XML editors. XML stands for Extensible Markup Language and was developed as a simpler subset of SGML to enable use on the web. It allows users to define their own tags for structuring data versus using predefined tags like HTML.
XML (Extensible Markup Language) allows users to define their own customized markup languages to structure data. It was created as a simplified version of SGML to make it usable on the web. XML is important because it removes constraints of HTML and allows for richer content than HTML alone. XML will enable easier exchange of data between businesses and applications.
The document discusses XML schemas and their use in describing messages exchanged by web services. It provides an overview of XML schema components like elements, data types, and attributes. It also discusses how schemas are used to define the structure and rules for XML documents. The document then gives examples of managing WSDL and XML schema documents in a global cache, which improves performance for services that validate messages against cached schemas.
XML is a markup language similar to HTML but designed to carry data rather than display it. Unlike HTML, XML tags are user-defined rather than predefined. XML focuses on describing what data is, while HTML focuses on how data looks. XML allows data sharing across different applications and is commonly used to store and transport data on the web and in applications.

This document summarizes an article that proposes a system for compressing XML documents while still allowing queries to be efficiently evaluated on the compressed data. The system first compresses the XML document using the proposed algorithm, which divides the compressed file into different relational databases, eliminating the need to fully decompress the file for each query. Only the required information is decompressed and returned to the user. Experimental results on sample XML documents show that the system achieves competitive compression ratios compared to other query-capable XML compressors, and can efficiently answer different types of queries on multiple compressed documents with minimal decompression.
This document provides an introduction to XML. It discusses that XML stands for Extensible Markup Language and is a text-based markup language used to store and transport data. It also describes that XML documents have a .xml file extension and reference a DTD or schema that defines the document structure. The document then gives examples of XML tags, elements, and attributes to illustrate XML syntax and building blocks.
The .NET Framework provides classes for working with XML, including parsing, validation, navigation, schema management, transformation, and serialization. Key classes include XmlReader, XmlWriter, and XmlDocument. XML is used extensively in .NET for configuration, ADO.NET, remoting, web services, and more. The document outlines the XML parsing model in .NET and classes for reading, writing, and manipulating XML.
XML became a W3C recommendation in 1998. It is a subset of SGML that describes data objects called XML documents using tags that are not predefined. The goal of XML was to enable generic SGML to be served, received, and processed on the web in a way that was not possible with HTML by creating compulsory rules. XML documents consist of characters from Unicode and are divided into markup and content. They begin with an XML declaration and document type declaration and contain elements enclosing data content and attributes. Schemas and DTDs define elements, attributes, and structure for XML documents. Stylesheets like CSS and XSLT can transform XML into HTML for browser viewing. Current browsers support XML with associated stylesheets.
XML is a markup language similar to HTML but designed to carry and store data rather than display it. It was created based on SGML and allows users to define their own tags for structuring data. XML uses tags enclosed in angle brackets to mark up content. It is more flexible than HTML and focuses on describing data rather than pages. XML is useful for storing and exchanging complex structured data between different systems.
This document discusses XML, its components like DTDs, and applications. It describes XML as a flexible markup language that allows arbitrary tags to encode semantic data. XML documents can be well-formed or validated against DTDs. Popular APIs like DOM and SAX allow programmatic access to XML documents. While XML is human-readable and widely adopted, its text-based nature uses more space and standardization remains a work in progress. The document also outlines evolving recommendations, industry XML databases, query languages, and how XML relates to systems research issues.
LINQ (Language Integrated Query) allows adding querying capabilities to .NET languages. It defines standard query operators and translation rules to query data like arrays, XML, databases. LINQ to XML represents XML as XElement objects that can be queried using LINQ. The System.Xml.Linq namespace contains classes like XDocument and XElement for constructing XML documents programmatically. XML can be loaded from files, traversed, inserted, deleted, and updated using LINQ to XML.
This document provides an introduction to XML, including:
1) XML is a markup language that allows users to define their own tags to structure data for exchange and manipulation. It complements HTML by allowing structured data marking.
2) The tutorial covers the history and goals of XML, the basics of tags, elements, and attributes, document type definitions (DTDs), and other XML concepts to help readers understand XML.
3) The objectives are to discuss what XML is, how and why it was developed, its basic structure, how XML documents are read, and how XML may be used to provide e-commerce solutions.
This document proposes a fuzzy rule-based approach for transcoding HTML documents to make them suitable for display on mobile devices. Key points:
1. HTML documents often contain elements like frames and tables that do not adapt well to small mobile displays. Transcoding restructures documents to better fit limited mobile screens.
2. Transcoding depends on device profiles like screen size and user preferences. However, profiles and preferences can be imprecise. The approach uses fuzzy sets and rules to handle vagueness.
3. A fuzzy rule language called Fuzzy-RDL/TT specifies transcoding functions and selects them based on fuzzy comparisons of user/device profiles to predefined sets. This allows adaptive transcoding based

Universal Business Language (UBL) aims to define a standard XML vocabulary for business documents that fulfills the promise of XML for e-business. UBL provides a standard set of XML business documents that can enable the next generation of EDI by making it cheaper, easier, and allowing its use over the Internet. UBL documents can also extend the benefits of EDI to small businesses by fitting existing legal and trade concepts and allowing reuse of data. UBL is committed to international standards like ebXML Core Components to ensure interoperability.
The document provides an introduction to XML, explaining that it is a text-based markup language used for data interchange on the web. XML tags identify and label pieces of data, rather than specifying how to display it like HTML tags. Tags can also include attributes to provide additional information. The document gives an example of XML markup for a messaging application to demonstrate how hierarchical data can be represented using nested tags.
The document discusses Open Document Format (ODF) which aims to make office documents more accessible and interoperable by being based on open standards like XML, ZIP, and CSS. It describes how ODF files can be programmatically processed at different levels of abstraction from direct XML to object models. Frameworks like odf4j and AODL provide ODF support for Java and .NET respectively, hiding some of the XML complexity and exposing ODF semantics. Future work areas include harmonizing ODF toolkits and extending ODF through new metadata mechanisms.
The document discusses legacy connectivity and protocols. It describes legacy integration as integrating J2EE components with legacy systems. The key approaches to legacy integration are data level integration, application interface integration, method level integration, and user interface level integration. Legacy connectivity can be achieved using Java Native Interface (JNI), J2EE Connector Architecture, and web services. JNI allows Java code to call native methods written in other languages like C/C++. The J2EE Connector Architecture standardizes connectivity through resource adapters. Web services provide a platform-independent approach through XML protocols.
The document discusses messaging and internationalization. It covers messaging using Java Message Service (JMS), including the need for messaging, messaging architecture, types of messaging, messaging models, messaging servers, components of a JMS application, developing effective messaging solutions, and implementing JMS. It also discusses internationalizing J2EE applications.
The document discusses Java 2 Enterprise Edition (J2EE) application security. It covers security threat assessment, the Java 2 security model, and Java security APIs. The Java 2 security model provides access controls and allows downloading and running applications securely. It uses techniques like cryptography, digital signatures, and SSL.

inQuba Webinar Mastering Customer Journey Management with Dr Graham HillLizaNolte
HERE IS YOUR WEBINAR CONTENT! 'Mastering Customer Journey Management with Dr. Graham Hill'. We hope you find the webinar recording both insightful and enjoyable.
In this webinar, we explored essential aspects of Customer Journey Management and personalization. Here’s a summary of the key insights and topics discussed:
Key Takeaways:
Understanding the Customer Journey: Dr. Hill emphasized the importance of mapping and understanding the complete customer journey to identify touchpoints and opportunities for improvement.
Personalization Strategies: We discussed how to leverage data and insights to create personalized experiences that resonate with customers.
Technology Integration: Insights were shared on how inQuba’s advanced technology can streamline customer interactions and drive operational efficiency.
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

1. Extensible Markup Language
Rationale
• Data interchange is essential to carry out business
transactions. However, organizations store data in disparate
formats, which makes the process of data interchange
complex and time-consuming.
• Extensible Markup Language (XML) is a standard, simple
way of storing the data in a format that can be exchanged
across multiple systems across an enterprise. Providing an
insight into XML will benefit students as it is a standard
technology to describe and define documents.
• The course is applicable to students who want to create
well-formed XML documents. This course introduces
students to the fundamentals of XML and enable them to
effectively use XML as a markup language to develop Web
applications.

3. Extensible Markup Language
Getting Started with XML
Traditionally, preprinted formats were used to exchange
information between businesses.
Need for a more effective way of communicating and
processing business data led to the emergence of
Electronic Data Interchange (EDI).
EDI refers to the process of exchanging documents in a
standard format between two computer systems.
EDI has the following limitations:
Rigid transaction set
Fixed business rules
High costs
Slow pace of standards evolution

Introducing XML
XML is a text-based markup language that enables storage
of data in a structured format.
XML is a cross-platform, hardware and software
independent markup language that enables structured data
transfer between heterogeneous systems.
XML is used as a common data interchange format in a
number of applications.

Web Architecture Using XML
In a traditional Web architecture, a client sends a request to
the server in a pre-defined format and receives the response
accordingly.
The advantage of using XML in the Web architecture is that the
structure of the request can be obtained from the server at run
time.
XML can encode non-relational data as well as relational data
structure.

Difference Between SGML, HTML, and XML
Standard Generalized Markup Language (SGML) allows
documents to describe their grammar by specifying the tag set
used in the document and the structural relationship that these
tags represent.
Hypertext Markup Language (HTML) is used for data
presentation.
XML is used for data description and definition.

the three branches maintain data on their local computer
systems. The IT manager at CyberShoppe has identified that a
centralized data repository on the products sold through its
e-commerce site is required. The data from all branches must
be collated and housed in a centralized location. This data
must be made available to the Accounts and Sales sections at
the individual branches, regardless of the hardware and
software platforms being used at the branches.
In addition, the sales personnel require access to the data
using palmtops and cellular phones. The product details of
CyberShoppe consist of the product name, a brief description,
the price, and the available quantity on hand. A product ID
uniquely identifies each product.

Summary (Contd.)
In future, XML will be widely used in:
E-commerce
B2B services
Mobile services
EDI and EAI
XML was defined by W3C to ensure that structured data is
uniform and independent of vendors and applications.
In XML, an information model is used to understand the
structure and meaning of information that will be stored in XML
documents.
You can create static, dynamic, or a combination of both these
information models for an XML application.
A static information model helps you define all the objects in an
application and the relationships among them.

Editor's Notes
Students have learnt the structure of different types of dimensions and the importance of surrogate keys in Module I. In this session, students will learn to load the data into the dimension tables after the data has been transformed in the transformation phase. In addition, students will also learn to update data into these dimension tables. Students already know about different types of dimension tables. Therefore, you can start the session by recapitulating the concepts. Initiate the class by asking the following questions: 1. What are the different types of dimensions? 2. Define flat dimension. 3. What are conformed dimension? 4. Define large dimension. 5. Define small dimension. 6. What is the importance of surrogate key in a dimension table? Students will learn the loading and update strategies theoretically in this session. The demonstration to load and update the data in the dimension table will be covered in next session.
Introduce the students to the course by asking them what they know about forensics. Next, ask the students what they know about system forensics and why is it required in organizations dependent on IT. This could be a brief discussion of about 5 minutes. Lead the discussion to the objectives of this chapter.
Introduce the students to the different types of threats that systems face by: Asking the students to give examples of what they think are environmental and human threats. Asking the students to give instances of what they think are malicious and non-malicious threats. Conclude the discussion on the different types of threats by giving additional examples of malicious and non malicious threats.
Hold a two- three minute discussion on the different types of system-related crimes that the students have experienced or heard. At the end of the discussion, give additional examples of system-related crimes.
While explaining the definition of system forensics, ask the students to note the following key words in the definition: Identify Extract Process Analyze Digital and hardware evidence Tell the students that these form an integral aspect of system forensics and would be discussed in detail. Before moving on to the next slide, hold a brief discussion on why is it important for organizations to take the help of system forensics. The discussion should be focused on: The role that system forensics plays in organizations having an IT set up. This discussion will serve as a precursor to the next slide.

Elaborate on the role that system forensics plays in an organization, based on the discussion in the previous slide and the information given on this slide.
Explain to the students that a system can be secured by sealing the system(s) that have been a part of the crime. This involves: Immediately sealing the system by removing the hard disk and other components of the system. Ensuring that no other routine activity is conducted, using any component of the system. Taking snapshots and back ups of all digital evidences such as documents, system files, and e-mails. Tell the students that the ‘chain of evidence’ is most critical to a system forensic investigation. It helps in reconstructing a crime occurred from the beginning to the end.
