 Any model can be saved as an EGOML document. The resulting file uses the extension ".egoml" (the old extension ".xml" is still supported for backward compatibility). See [[basic_data_flow|Basic Data Flow]] for the execution model shared by EGOML and [[ego_script|EGO Script]]; this page covers the XML notation specifically.
-The EGOML file is an XML document written according to the following DTD; see [[https://skew.org/xml/tutorial/|skew.org's XML tutorial]] for a good introduction to the DTD description syntax:

-The property keys are always fully expanded. There is no property alias as in the [[ego_script|EGO Script]] format.
+==== Elements ====
+Each element in the DTD corresponds directly to a piece of the underlying functor graph described in [[basic_data_flow|Basic Data Flow]]:
+  * ''script'' is the model as a whole — the root element, holding the model's own properties plus every top-level functor and container.
+  * ''functor'' is a single functor call, identified by its ''name'' attribute (such as ''LoadMap''). It holds its own properties, its input ports, and its output ports.
+  * ''containerfunctor'' is a functor that also holds nested functors and containers — the same element type can nest inside itself, since containers can be placed inside other containers.
+  * ''property'' attaches metadata to whatever element contains it, as a ''key''/''value'' pair. Keys are always written fully expanded — there is no property alias as in the [[ego_script|EGO Script]] format.
+  * ''inputport'' and ''outputport'' are a functor's connection points. An ''outputport'' declares an ''id''; an ''inputport'' elsewhere in the document references that ''id'' through its own ''peerid'' attribute to form a connection — the XML equivalent of two functors sharing a variable name in EGO Script.
+  * ''internalinputport'' and ''internaloutputport'' work the same way, but connect a container to the functors nested inside it, rather than connecting two ordinary functors to each other.
+The DTD defines no equivalent of EGO Script's abbreviated calculator syntax. Every functor in the Calculate family — ''CalculateMap'', ''CalculateLookupTableValues'', and the others — is represented the same way as any other container: its operands are connected through explicit ''NumberMap''/''NumberTable''/''NumberValue'' hook functors, as shown in the ''CalculateMap'' example below. See [[ego_script#calculator_functor_shorthand|Calculator functor shorthand]] for the two syntactic forms EGO Script provides for this same underlying structure.
