Using the Assistant

5. Define the words or phrases this template is to match as an array of strings in its

lexicon

slot. If you place the name of a system-supplied template in your

template's

isa

slot, your template inherits its lexicon from the system-supplied

template. You should be aware, however that

isa

slot values other than the

symbols

'dyna_user_action

and

'dyna_user_obj

may interfere

with the system's ability to match your template successfully. For more
information, see the section "Defining Your Own Frame Types to the Assistant,"
immediately following.

The following code fragment defines an action template called

myPayAction

that

might be used by a home banking application:

myPayAction := {

value:

"Pay Action",

// name of action

isa:

'dyna_user_action

// must use this value

lexicon: ["pay", "paid"]

// words to match

}

The following code fragment defines a target template called

cbPayee

that a

home banking application might use:

myPayee := {

value:

"Who Object",

// name of target

isa:

'dyna_user_obj

// must use this value

lexicon: ["to", "Bob"]

// words to match

}

The conflict resolution mechanism relies on the use of system-supplied dynamic
user object templates. You can define your own symbol for your template's

isa

slot as long as it ultimately refers to a template with the symbol

'dyna_user_action

or

'dyna_user_obj

as the value of its

isa

slot. For example, you can define a

my_action

template that is a

'dyna_user_action

, as shown in the following code fragment:

my_action := {

value:

"my action"

// name of this action

isa:

'dyna_user_action,

// must use this value

lexicon: ["jump", "hop"]

// words to match action

}
