Application
This unit describes the skills and knowledge required to create extensible markup language (XML) documents, web-service applications, and client applications to consume web services.
It applies to individuals who are web developers, web programmers or application programmers, who build Windows or web-based applications that access data in XML format, or who develop and consume web services.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Represent the structured data with XML | 1.1 Gather information by analysing data, documents, and problem domains 1.2 Write a well-formed XML document by incorporating the appropriate structure and syntax 1.3 Validate the XML document using validation tools 1.4 Format the XML document using styling tools |
2. Access and manipulate the XML document | 2.1 Create a new XML document using an XML parser application programming interface (API) 2.2 Access and traverse elements, and attributes, using an XML parser API 2.3 Modify elements and attributes using an XML parser API 2.4 Delete elements and attributes using an XML parser API 2.5 Transform the XML document into a data object, using an XML parser API 2.6 Transform the data object into an XML document, using an XML parser API |
3. Create a service-oriented application using XML | 3.1 Define the web-services architecture and platform elements 3.2 Develop and deploy web-service applications using a language 3.3 Develop a client application to consume web service, using a language |
Evidence of Performance
Evidence of the ability to:
gather relevant information and produce a well-formed, formatted and validated XML document
use an XML parser to access, modify and transform the XML documentation
create a service-oriented application using XML.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
outline the hierarchy and tree structure
explain the programming concept and language
describe the main features and services of the world wide web (WWW)
explain data modelling
outline commonly used items in hypertext markup language (HTML)
identify information system features
identify source characteristics.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the programming and software development industry, and include access to:
tools to access and develop a data source, such as an integrated development environment (IDE), a text editor and a web browser
specific requirements, including client and functionality requirements
a web server and software that hosts the services to deploy and test, the web-service application
libraries to develop the web service and client applications.
Assessors must satisfy NVR/AQTF assessor requirements.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
Skill | Performance Criteria | Description |
Reading | 1.1 | Interprets and critically analyses, and applies the appropriate strategies, to construct meaning when gathering information by analysing data, documents and problem domains |
Writing | 1.2, 1.4, 2.1, 2.3, 2.5, 2.6 | Prepares documentation expressing ideas, explores complex issues, and is constructed logically, succinctly and accurately Writes, and edits, computer code and technical data, ensuring the correct syntax and accuracy |
Numeracy | 1.2 | Selects from, and applies, an expanding range of mathematical and problem-solving strategies in a range of contexts, identifying the order and position of elements in a sequence, when using XML |
Get the work done | All | Uses systematic, analytical processes in complex, non-routine situations, setting goals, gathering relevant information and identifying, and evaluating, options against the agreed criteria Applies formal problem-solving processes when tackling an unfamiliar problem, breaking complex issues into manageable parts and identifying, and evaluating, several options for action Utilises a broad range of features within applications to improve personal productivity, and optimising software functions for specific purposes |
Range Statement
This section specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Structure must include: | child element root element sub-child element. |
Syntax must use rules relating to: | case sensitivity closing tag entity reference proper nesting quoted attribute values single-root element. |
