2.2. Useful markers and useless markers
Document Actions
When using Toolbox you usually have a number of predefined markers to choose from for your project. The predefined set is called the MDF (Multi-Dictionary Formater). It is very advisable to use them, so that working with your lexicon is easier for people not that familiar with your project. It is simply a question of uniformity and comparability between different lexicons. Naturally, it might not always be possible, as your project might need some elements particular to that lexicon only, but as far as it possible is it is a very good idea.
However, it will more often be the case that you will actually not make use of some markers from the predefined list, rather then add some of your own. In that case, it is advisable to erase those markers that you are not using from the list of markers in Toolbox. Simply keep in your structure file only those markers that you are actually making use of.
Thirdly, if you decide to include a marker in your project, make sure that it has not only a symbol (e.g.), but also a name (e.g. ). It is also highly advisable to give descriptions to your markers, especially if you have introduced some new markers, potentially unknown to others. Giving a name to your markers is not only a practical idea, but it is necessary for the import of the .typ file into LEXUS. LEXUS will recognize markers that do not have names. However, such markers will be included in the structure without names. If there will be more than one such marker in your file, it might be difficult later to find out which one is which.
Giving descriptions to your markers is not a prerequisite for import into LEXUS, but be aware that you might want to ask other people, for instance the LEXUS technical group to run tests for your data in LEXUS to see how it works. In that case, it is sometimes very helpful in solving potential problems to know what a particular marker is actually supposed to stand for.
