Indexes (%) are used for co-indexing nodes, attributes and values inside and between the left and the right side of [[T-rule]]s and [[N-rule]]s.

== Use ==
:X(%a;)Y(%a;) (the first node of X is also the first node of Y)
:X(%a;%b):=Y(%b;%a); (the first node of X becomes the second node of Y, and the second node of X becomes the first node of Y)
:X(%a;)Y(%a;):=Z(%a); (if the first node of X is the first node of Y then make it the single node of Z)
<blockquote>Any co-indexation is made by the use of indexes and not by the repetition of features. In that sense, '''X(A;)Y(A;)''' is different from '''X(%a;)Y(%a;)'''. In the former case, the first node of X is not necessarily the first node of Y, they only share the same feature A; in the latter case, the first node of X is necessarily the first node of Y.</blockquote>
;
;Indexes may also be used to transfer attribute values expressed in the format ATTRIBUTE=VALUE:
:X(A,%a,ATT1=VAL1;B,%b):=X(%a;%b,ATT1=%a); (the value "VAL1" of "ATT1" of %a is copied to the node %b)

== Syntax ==
Indexes are made of any sequence of alphanumeric characters and underscore preceded by %:
:%index
:%a
:%first_index
:%a1
:<strike>%first index</strike> (no blank spaces are allowed)
<blockquote>%01 (numbers are used for default indexation and must be avoided - see below)</blockquote>

== Indexation ==
;Default indexation
:If omitted, indexes are assigned by default, according to the following rules:
:Default indexes are assigned from left to right in each side of the rule according to the position of the nodes:
::X(A;B)Y(C;D) is the same as X('''%01''',A;'''%02''',B)Y('''%03''',C;'''%04''',D)
:Default indexation is done only for non-indexed nodes (i.e., user-defined indexes prevail over indexes assigned by default):
::X(A,%A;B)Y(C,%C;D) is the same as X(A,%A;B,'''%02''')Y(C,%C;'''%04''',D)
:::(Notice that the user-defined indexes %A and %C are preserved and not replaced by default indexes)
:In default indexation, left-side nodes are automatically co-indexed with right-side nodes '''if and only if''' their position and number are the same:
::X(A;B):=Y(C;D); is the same as X('''%01''',A;'''%02''',B):=Y('''%01''',C;'''%02''',D);
::X(A;B):=Y(C;D;E); is the same as X('''%01''',A;'''%02''',B):=Y('''%03''',C;'''%04''',D;'''%05''',E);
:::(there is no co-indexation between the left and the right side in the latter case, because the number of the nodes is not the same)
:Default indexes are also assigned to hyper-nodes and sub-nodes
::(((A))):=(((B))); is the same as (%01(%01%01(%01%01%01,A))):=(%01(%01%01(%01%01%01,B)));
:In default indexation, sub-nodes are informed by the syntax <PARENT NODE><CHILD NODE>, where <PARENT NODE> may be, itself, a sub-node:
::X(Y(A;B);C) is the same as X('''%01''',Y('''%01%01''',A;'''%01%02''',B);'''%02''')
:::%01 = Y(A;B), %02 = C, %01%01 = A, %01%02 = B
::X(Y(Z(A;B);C);D) is the same as X('''%01''',Y('''%01%01''',Z('''%01%01%01''',A;'''%01%01%02''',B);'''%01%02''',C);'''%02''',D)
:::%01 = Y(Z(A;B);C), %02 = D, %01%01 = Z(A;B), %01%02 = C, %01%01%01 = A, %01%01%02 = B
;Non-indexed nodes in the right side means ADDITION, whereas left-side nodes that are not referred to in the right side means DELETION
:X(%a;%b):=Y(%a;X;%b); is the same as X(%a;%b):=Y(%a;'''%02''',X,;%b); (it means that a new node with the feature X will be created for the relation Y)
:X(%a;%b;%c):=Y(%a;%c); (it means that the second node of X will be deleted from the relation Y)

== Compound NLWs ==
;Special indexes (#) are used to make reference to the internal structure of the field <NLW> in the dictionary
:(X)(Y):=(X,#02)(Y)(X,#01);
::The rule above is used for complex dictionary entries such as:
:::[[A][B]] "uw" (X, #01(ATT=AAA), #02(ATT=BBB)) <flg,fre,pri>;
::It means that, given (X)(Y), the output should be (B)(Y)(A).
