====== EGOML Script ======

===== Overview =====

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:

<code dtd>
<?xml version="1.0"?>
<!DOCTYPE script [
  <!ELEMENT script (property*, functor*, containerfunctor*)>
 
  <!ELEMENT functor (property*, inputport*, outputport*)>
    <!ATTLIST functor
      name   CDATA  #REQUIRED>
 
  <!ELEMENT containerfunctor (property*, inputport*, outputport*, internalinputport*, internaloutputport*, (functor|containerfunctor)*)>
    <!ATTLIST containerfunctor
      name   CDATA  #REQUIRED>
 
  <!ELEMENT property EMPTY>
    <!ATTLIST property
      key  CDATA  #REQUIRED
      value  CDATA  #REQUIRED>
 
  <!ELEMENT inputport (#PCDATA)>
    <!ATTLIST inputport
      name   CDATA  #REQUIRED
      peerid IDREFS #IMPLIED>
  <!ELEMENT outputport EMPTY>
    <!ATTLIST outputport
      name   CDATA  #REQUIRED
      id   ID   #REQUIRED>
   <!ELEMENT internalinputport EMPTY>
    <!ATTLIST internalinputport
      name   CDATA  #REQUIRED
      peerid IDREFS #IMPLIED>
  <!ELEMENT internaloutputport EMPTY>
    <!ATTLIST internaloutputport
      name   CDATA  #REQUIRED
      id   ID   #REQUIRED>
]>
</code>

The property keys are always fully expanded. There is no property alias as in the [[ego_script|EGO Script]] format.

Below is an example of an EGOML script used to load a map, calculate an image convolution, and save the result:
