The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the ability to: produce, validate, transform, format and transport XML data exchange data between different applications and different platforms by creating and consuming web services. |
Context of and specific resources for assessment | Assessment must ensure access to: tools in accessing and developing a data source, such as integrated development environment (IDE), text editor and web browser specific requirements, including client and functionality requirements web server and software that host services to deploy and test web service application libraries to develop web service and client applications, such as SOAP libraries appropriate learning and assessment support when required modified equipment for people with special needs. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: evaluation of ability to: develop XML applications to generate a report in HTML or portable document format (PDF) file by applying certain presentation style using styling tools develop web or stand-alone applications that access and store information in XML data format develop and consume web service applications to solve interoperability problem by writing client code in different platform verbal or written questioning to assess candidate’s knowledge of XML. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Structure must include: | child element root element sub-child element. |
Syntax must include these rules: | case sensitive closing tag entity reference proper nesting quoted attribute values single-root element. |
Validation tools may include: | document type definition (DTD) validating parsers XML schema XSD schema validator. |
Styling tools may include: | cascading style sheets (CSS) eXtensible stylesheet language (XSL) eXtensible stylesheet language transformations (XSLT). |
XML parser application programming interface may include: | data binding document object model (DOM) language-specific API, such as XML API in .NET, JAXP in Java, and E4X in ActionScript simple API for XML (SAX) XMLPULL. |
Platform elements may include: | simple object access protocol (SOAP) universal description, discovery and integration (UDDI) web services description language (WSDL). |
Language may include: | Java Net languages PHP Python. |
