List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Use XML to provide information | 1.1 Create XML data structures from various data sources 1.2 Manipulate XML data structures, using a common application programming interface (API) 1.3 Use namespaces to scope elements from multiple XML documents 1.4 Validate XML data structures, using a schema 1.5 Map, and transform, an XML document from one schema to another |
2. Use WSDL to promote a web service | 2.1 Understand the purpose of the web service description language (WSDL) 2.2 Identify the three main elements that comprise WSDL 2.3 Build a WSDL file 2.4 Provide web access to a WSDL file, via a uniform resource locator (URL) |
3. Use UDDI to locate and retrieve information about a public web service | 3.1 Identify the purpose of universal description, discovery and integration (UDDI) 3.2 Understand the differences between public, extra-enterprise and intra-enterprise, UDDI registry deployments 3.3 Locate, and retrieve information, about a public web service using UDDI 3.4 Identify the relationship between WSDL and UDDI |
4. Access the web services using SOAP | 4.1 Identify the purpose of simple object access protocol (SOAP) 4.2 Determine the relationship between UDDI and SOAP 4.3 Identify the basic structure and processing of a SOAP message 4.4 Retrieve an XML document from a public web service, using SOAP |
5. Implement a web service | 5.1 Outline a basic web service architecture 5.2 Implement, test and publish a web service 5.3 Incorporate and test a web service into an application |
Evidence of the ability to:
transform data from relational or other native data sources, into an extensible markup language (XML)
validate an XML document, using a predefined schema
provide access to the business functionality via a web service description language (WSDL) file
locate a public web service business function, and include it in a website, using universal description, discovery and integration (UDDI), and a simple object access protocol (SOAP)
implement a web service according to the business requirements, specifications, and industry standards.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
To complete the unit requirements safely and effectively, the individual must:
summarise integrated development environments
summarise web development technologies
outline the web service architecture
describe the importance of XML language and data structures.
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 website technologies field of work, and include access to:
the web service business requirement specifications
industry standards published by the World Wide Web Consortium (W3C)
platform-specific documentation and help files, describing the syntax and use of proprietary technologies
a simulated development environment, incorporating the following elements:
a relational database server
the integrated development environment (IDE), including related frameworks, APIs and associated proprietary classes, required to implement web services and their enabling technologies
a web server
web browsers
XML editors
XPath testing utilities.
Assessors must satisfy NVR/AQTF assessor requirements.
