This schema specifies the format for describing a BrainML interface for querying or submitting to a BrainML data server. An instance document conforming to this schema describes a "view" on the data structure defined by a BrainML data model. The view refers to and incorporates elements from a BrainML model in a specified configuration adding user interface information including: () elements to show or hide; () instructional or descriptive material for elements; () display layout hints. Views are used to describe both web and graphical application interfaces. Root element for a model view document. Contains a collection of pages. Specifies the model this view is for. Base namespace for model element references beneath this item. Specifies a "page" in this view. In a web interface, this might correspond to an actual web page. In a workstation application, this might correspond to a window or tab-pane. Contains a collection of items. Identifier for the page, used by software to track it. Should be unique within the document. Whether the fields with the same name under different items beneath this page should be merged and shown as a single field. This is most useful for query interfaces where, for example, several items might have a 'last_name' field but the user does not care about the distinction between them and just wants to search by name. Whether the fields for items beneath this page should be grouped together or split into sections by item. Base namespace for model element references beneath this page. Specifies an item in the view, corresponding to a BrainML entity. Identifier for item. This is used by the software processing view a view document to index this item. It should be unique within the container. If an id is not specified, the name of this item is used instead. Namespace (BrainML model URN) of this item. If unspecified, the prevailing xml:base from the container or ancestor is used. The item's name in the model. Base namespace for model element references beneath this item. Use to override what is specified in the model, or for top-level items whose container cannot be determined (if not specified, will default to minOccurs = maxOccurs = 1). Both minOccurs and maxOccurs must be present here if either is. Use to override what is specified in the model, or for top-level items whose container cannot be determined (if not specified, will default to minOccurs = maxOccurs = 1). Both minOccurs and maxOccurs must be present here if either is. If true, item will be displayed internally to parent item, as if it were a labeled subset of its fields, rather than a hierarchically contained member. If true, item will be displayed as a list item with other siblings of same type, rather than individually. User interface category. This may be used to specify that special rendering should be used for this field. The value must be recognized by the software doing the rendering or it will be ignored. Contains text providing any description or special instructions pertaining to an item. In addition, if child "add" is present, its contents will be used to provide instructions when presenting the option to ADD an item of this type to the structure. Instructions to use when interface presents option to add a new item of this type. Contains a collection of fields that should be presented as a unit. Identifier for group. Required since there is no name. Specifies a field of a model entity to be displayed under a view item. Identifier for field. This is used by the software processing view a view document to index this item. It should be unique within the item. If an id is not specified, the name of this field is used instead. The field's name in the model. Boolean attribute (valid values: { 'true', 'false' }) specifying whether this field MUST take on a value in an instance. Specifies the number of columns this field's value should be given in a columnar user interface display. Value to assume for field if not given. Value to initialize field to (e.g. in user interface form). User interface category. This may be used to specify that special rendering should be used for this field. The value must be recognized by the software doing the rendering or it will be ignored. Set false if this field may NOT be used in a template to fill out other copies of this object. For example, when submitting data, if more than one instance of this object can occur, but the value on this field is often shared between them, it is left true. If the data is always unique per-item, explicitly set to false. Use to override what is specified in the model. * Both minOccurs and maxOccurs must be present here if either is. Use to override what is specified in the model. * Both minOccurs and maxOccurs must be present here if either is. Specifies that one of a view entity's linked entities in the model should be exposed to the user, so they may choose entities in a view instance to link to. Identifier for link set. This is used by the software processing view a view document to index this item, and to present a display name to the user. It should be unique within the containing item, and inform the user as to the usage of this type of link. Value should be a comma-separated list of IDs used elsewhere in this file. Use to override what is specified in the model. * Both minOccurs and maxOccurs must be present here if either is. Use to override what is specified in the model. * Both minOccurs and maxOccurs must be present here if either is. Specifies an external link to a resource. The text of the link is created by substituting a field's value for the value '$$$' in refTemplate. External links can be made from either entities (in which case the fieldName attribute must be specified) or fields (fieldName is implied and should be left blank). The link will be rendered in a form appropriate to the view's display. For example, in an HTML-based display, a hyperlink will be rendered. Template for reference. The value '%%%' will be substituted by field's value for final reference. ('%%%' may be absent.) Template for displaying reference. The value '%%%' will be substituted by field's value for final reference. ('%%%' may be absent.) Specifies whether external link should be displayed at level of item. If true, the link will be displayed at the item level; if false or absent, link will be displayed at field itself. Separator marker akin to HTML specifying a line break in the user interface display.
