Flying Logic Document Format

Flying Logic documents are XML-formatted files. The schema for release 4 documents can be downloaded here. Following are some supporting tables explaining more about the schema.

Reference Tables

The table below gives information about each XML element that can be found in a Flying Logic document. The elements are listed in the order they generally appear in a document. The attributes and attribute elements are common children of many elements, so those elements and their children are documented at the end of this table. Because the words “attributes” and “attribute” are used as element names in a Flying Logic document, those words will be shown in a fixed-width font when referring to the element names and not as an XML attribute value.

Element	Description
flyingLogic	The root element. Attributes are majorversion (required, “5” for Flying Logic 4.X), minorversion, uuid, and instance. Can contain domains, symbols, displaySettings, canvasSettings, inspectorSettings, printSettings, documentInfo and decisionGraph elements. During XSLT export will also contain an exportDocumentInfo element.
domains	The custom domains defined in the document. Can contain domain and alteredBuiltinDomain elements.
domain	A custom domain. Contains entityclass and attributes elements.
entityclass	Either a custom entity class in a domain or a reference to an entity class as an entity attribute. For a custom entity class, contain an attributes element. For a reference, has required XML attributes name and uuid.
alteredBulltinDomain	Appears when a built-in domain is hidden. Required attributes are domainName and entityClass (the guid of one entity class in the domain). Contains an attributes element.
symbols	The custom symbols defined in this document. Can contain symbol elements.
symbol	Either a custom symbol or a reference to a symbol as an entity or group attribute. Required attributes are generator and idCode. A custom symbol definition will contain either additional elements or text depending on the format of the custom symbol, and can have a clip element. Bitmap image symbols contain a base-64 encoded dump of a PNG file as text.
clip	A clip rectangle for a symbol. If missing, the default is the whole “image.” Required attributes are x, y, width and height.
data	Appears in an SVG symbol. Contains a CDATA with the XML text from an SVG file.
displaySettings	The visual elements and layout of the graph. All the attributes are optional: addEntityAsSuccessor, annotationToBrowse, bias, confidenceVisible, edgeNotesVisible, edgeWeightsVisible, entityIdVisible, noteNumbersVisible, orientation, and projectManagementVisible.
canvasSettings	The scroll position and zoom level of the graph. Optional attributes are horizScroll, vertScroll and zoom.
chartSettings	The column visibility and with settings for chart view. All the attributes are optional: classVisible, classWidth, completionVisible, effortVisible, finishDateVisible, resourceVisible, resourceWidth, startDateVisible, and titleWidth.
inspectorSettings	This element has the state of the sidebar (inspector panel) and contains inspector elements. The attributes are visibility and width.
inspector	State information about an inspector. The title attribute matches the internal name of one inspector. The optional attributes are visibility and height. Only the Domain, Text and User-Defined Attributes inspectors have a height.
printSettings	Saved printing settings for the document. Optional attributes are footerLeft, footerMiddle, footerRight, headerLeft, headerMiddle, headerRight, paperMargins, paperName, paperOrientation, paperSize, saveInk and showselhalo. (Yes, showselhalo is all lowercase.)
documentInfo	Has attributes for some of the values settable the Document inspector: author, comments, keywords and title.
decisionGraph	The actual graph. Contains entityOperator, defaultJunctorOperator and logicGraph elements.
entityOperator	The current entity operator for the graph. The class attribute is the name of a vertex operator. See notes about vertex operators at after this table.
defaultJunctorOperator	The current default junctor operator for newly created junctors. The class attribute is the name of a vertex operator. See notes about vertex operators at after this table.
calendars	The calendars defined in the document. Can be missing if project management has never been enabled for the document. Contains one or more indexed element elements that themselves contain a workdays element. See com.flyinglogic.app.project.Workweek in table below for details.
resources	The resources defined in the document. Can be missing if no resources are defined. Contains one or more indexed element elements that themselves contain a resource element. See com.flyinglogic.app.project.Resource in table below for details.
logicGraph	The organization of the graph. Contains a operatorFamily and graph element.
operatorFamily	The key-value family of the graph. Has one required attribute class with a required value of com.flyinglogic.decisiongraph. DecisionGraphOperatorFamily.
graph	The elements of the graph. Contains attributes, vertices and edges elements.
vertices	Contains vertex elements representing entities, junctors and groups.
vertex	An entity, junctor or group. Has a required attribute of eid, an unique integer assigned to each graph element. Entities and junctors have optional attributes of inEdgeOrder and outEdgeOrder, which are space-delimited list of eid values for edges connected to the element. Groups have a grouped attribute, a space-delimited list of eid values for child vertices, and an optional collapsed attribute which has a value of true is the group is collapsed. Contains an attributes element. During XSLT export can also contain an exportAttributes element.
edges	Contains edge elements.
edge	An edge. Has three required attributes: eid, an unique integer assigned to each graph element; and source and target, the eid of the connected vertices. During XSLT export can also contain an exportAttributes element.
attributes	Contains attribute elements.
attribute	An attribute is a key-value pair with an associated data type for the value. There are two required attributes, key and class. Each known class has its own format for its contents. See the table of recognized classes below.
extendedDocumentInfo	This element only appears during XSLT export. Has attributes title (the document file name as a title), screenWidth and screenHeight (visible dimensions of graph) and hoistKey (eid of hoisted group if graph hoisted).
exportAttributes	This element only appears during XSLT export if the flags XSLT_INCLUDE_FRAMES or XSLT_INCLUDE_EDGE_SPLINES are set in the exportDocument call. Contains exportAttribute elements.
exportAttribute	A key-value pair with a key attribute and value of either text content or child elements. If XSLT_INCLUDE_FRAMES flag is set and a graph element is visible. it will have exportAttribute elements with values for x, y, width and height. If XSLT_INCLUDE_EDGE_SPLINES is set, a visible edge will have an exportAttribute with a key of path and contains a bezierList element.
bezierList	Has attributes of head and tail that indicate what the edge is connected to: source, target, annotation, weight, entityhoistcap or junctorhoistcap. Contains one or more bezier elements.
bezier	Has attributes giving the control points x1, y1, x2, y2, x3, y3, x4 and y4.

The contents of an attribute element varies by the value of the class attribute. The first table below lists all the know keys, the class for that key and the allowed parent element of the attributes element it appears within. The second table describes the contents for each recognized class. Operators have more details after these two tables.
