To modify an existing item in the structure, select the element in the structure in the left frame, the right frame opens in the Schema Element tab. You can modify all the previously added information about an item in the structure.

In case of Data Categories you may decide to change from the user-defined type of Data Category to the predefined Data Categories from the Toolbox MDF categories or the ISO 12620 registry. Changing to a Toolbox defined data category is useful in those cases where you need maximum interoperability between the newly created lexicon and lexica in your workspace which were imported from the Toolbox application. Changing to and ISO 12620 data category enhances interoperability and standardizes your lexicon to a wider accepted conceptual format.

To change to a Toolbox data category, select the element in the structure in the left frame. In the right frame, under Type click 'Toolbox'. Select the Toolbox data category from the list. Note that the description field will fill with information on the Toolbox element.

To change to an ISO 12620 element, select the element in the structure in the left frame. In the right frame, under Type click 'ISO12620'. Fill in the name of the data category in the search box, select in which repositories you want to search and select one of the elements from the search results (see Figure 2.3). In this example we replace the user created data category 'head word' by the ISO cat data category 'word'. A description of the data category is given in the search reslut list. For more detailed information on the data category a link to the ISOcat web site is given under the magnifier glass right of the search resluts.
