Lines Matching refs:field

27 **Simple Values**: You add simple values to the data block by adding a line like ''field: value''. The field and value are sometimes called the predicate and object respectively.
29 **Classes**: You can add one or more classes to a data block by placing them in the opening tag. Classes are separated by spaces, so class names declared in this way can not contain spaces. (Note that declaring a class name is effectively the same as adding a ''is a: person'' field-value pair to the data block.)
31 **Types**: You can add a [[#types|type]] to use by putting the type between ''['' and '']'' after the field name. Types determine how the data is displayed, and how it is stored.
36 -- Simple field-value pairs
50 **Empty values**: Any field that doesn't have a value is ignored. This way you can quickly write down some fields you want to use, but fill in their values later.
54 **Multiple Values**: You can have multiple values with a field. Do this by either putting a ''*'' after the field (or after the type, if it has any), or by simply adding the field multiple times.
71 **Patterns**: You can use variables and literals to describe what data you want to match. The patterns should be written down in lines, with each line formatted like ''subject field: value''.
73 For example, ''?p is a: person'' will match any subject that has field ''is a'' and value ''person'' to variable ''?p''.
160 The simplest form of data entry. Fields and values are also called predicates and objects. It is possible to leave out the value, then the field-value pair will not be stored, but you can easily fill in the missing value later.
173 Classes are not handled specially. This way of adding classes to the data is merely a convenience. You can achieve the same by adding values to field ''is a''. For example ''<data person>'' can be achieved by a line of ''is a: person'' in the data entry.
179 Normally, the ''entry title'' field is automatically generated for any data block. This field is used when displaying values with the [[#types|ref]] type.
181 The field is generated from the fragment identifier if it is available. If the block has no fragment identifier, the page title is used as entry title. If you want to override the entry title of a data block, you can do so by adding the ''entry title'' field yourself.
185 You can add a [[#types|type]] to a field by putting the type between ''['' and '']'' and placing it after the field name. This will change how the field's values are stored and displayed. Note that the declared type is only used during entry, that is, the type is not stored. You can declare a different type when [[#Querying Data]].
389 If a variable is not mentioned as one of the displayed fields, it will be ignored. You can hint that some field needs to be considered, but not displayed.
417   * ''text'': a text input field. It filters rows that have a value that contains the filter string (substring matching). E.g.: filtering for //David// will match //10 David Street//.
