2.1.8 Functionalities A MET must allow metadata records to be created, edited, copied, compiled, searched, saved and deleted in accordance with the standard Metadata Profile, including not only the mandatory elements but also the remainder of the standard’s elements. The basic functionality of the MET should cater for the needs of authors, users and managers of metadata. The MET should import and export different standards’ compliant metadata without the loss of content. To enable ease of human readability and presentation the MET should also produce valid text files such as HTML or RTF from the content of metadata. The application should also print metadata records using a print friendly layout. The tool should provide support for reuse and linkage of contact details. Normally contact details should be entered once, and re-used for all subsequent edits. This enables duplication of existing records for use as a first draft of a new metadata record. The tool should also be linked to the spatial application to be able to update the metadata when any change occurs to the spatial data. This significantly can reduce redundancies in the metadata database. More importantly the reliability of metadata linked to spatial data will increase. An integrated approach for handling metadata and spatial data together will require an integrated data model and integrated application. The ability to search for records using spatial, free text, keyword and other search terms through a simple or advanced search will increase the usability of the tool. The integrated help facility should also be available through the tool with table of contents, search facility and links to related web documents or websites, and a context help linking each of the elements to a summary and the detailed text of relevant sections of the user guidelines. Finally in a MET, the metadata administrator should be able to generate reports, statistical data based on specific metadata (elements), agency inputs, exports, and searches. Table 1 summarises the criteria developed for the assessment of metadata entry tools. 3. METADATA ENTRY TOOL ASSESSMENT A three stage methodology of assessment has been developed for evaluating a selection of metadata tools against the developed criteria. Figure 1 illustrates process flow and stages of the methodology. Stage 1 In this stage, a collection of related documents about the tools have been reviewed and explored. This stage helped with understanding of background and objectives of the tools development. The criteria developed above were finetuned in accordance with the overall purpose of the tools. Stage 2 In parallel to stage 1, the selected metadata entry tools were installed and the deployment process of each tool was investigated. Based on the results of the first stage, a questionnaire was developed and designed to be used by a number of five clients testing the user friendliness of each tool. The clients were selected from different background related to spatial science. 125

Functionality available, technical requirements and the tools user friendliness were explored. This section introduces the three metadata entry tools that have been studied and evaluated against the developed criteria. Each of these tools is explored in detail in this section, including background information essential to effectively assessing each of the tools in relation to the overall objectives of the article. 3.1 IDEC MetaD The Infraestructura de Dades Espacials de Catalunya (IDEC) project is a common initiative of the Cartographic Institute of Catalonia (ICC), the Department of Territorial policy and public works, the Secretariat for Telecommunications and Information Society, and the Department of Universities, Research and Information Society of the Generalitat de Catalunya, within the framework of the III Research Plan 2001-2004 and the Strategic Plan for the Information Society (Catalonia on the Network). Its aim is to create a Spatial Data Infrastructure for Catalunya (MetaD, 2007). Within IDEC initiatives, MetaD allows for the creation, edition and consultation of metadata stored in a data base. This includes the creation of new metadata records, as well as the maintenance of records already created. The tool incorporates various functionalities including an XML viewer. XML Viewer is a tool that allows the display of XML
