2 ## Identifier resolution
3
4 The schema may designate one or more fields as identifier fields to identify
5 specific objects. Processing must resolve relative identifiers to absolute
6 identifiers using the following rules:
7
8 * If an identifier URI begins with `#` it is a current document
9 fragment identifier. It is resolved relative to the base URI by
10 setting or replacing the fragment portion of the base URI.
11
12 * If an identifier URI contains `#` in some other position is a
13 relative URI with fragment identifier. It is resolved relative
14 to the base URI by stripping the last path segment from the base
15 URI and adding the identifier followed by the fragment.
16
17 * If an identifier URI does not contain a scheme and does not
18 contain `#` it is a parent relative fragment identifier.
19
20 * If an identifier URI is a parent relative fragment identifier
21 and the base URI does not contain a document fragment, set the
22 document fragment on the base URI.
23
24 * If an identifier URI is a parent relative fragment identifier
25 and the object containing this identifier is assigned to a
26 parent object field defined with `subscope` in
27 `jsonldPredicate`, append a slash `/` to the base URI fragment
28 followed by the value of the parent field `subscope`. Then
29 append the identifier as described in the next rule.
30
31 * If an identifier URI is a parent relative fragment identifier
32 and the base URI contains a document fragment, append a slash
33 `/` to the fragment followed by the identifier field to the
34 fragment portion of the base URI.
35
36 * If an identifier URI begins with a namespace prefix declared in
37 `$namespaces` followed by a colon `:`, the prefix and colon must be
38 replaced by the namespace declared in `$namespaces`.
39
40 * If an identifier URI is an absolute URI consisting of a scheme and path,
41 no processing occurs.
42
43 When preprocessing visits a node containing an identifier, that identifier
44 must be used as the base URI to process child nodes.
45
46 It is an error for more than one object in a document to have the same
47 absolute URI.

49 ### Identifier resolution example
50
51 Given the following schema:
52
53 ```
54 - $include: ident_res_schema.yml
55 - |
56 ```
57
58 Process the following example:
59
60 ```
61 - $include: ident_res_src.yml
62 - |
63 ```
64
65 This becomes:
66
67 ```
68 - $include: ident_res_proc.yml
69 - |
70 ```
