    11  # Declarative-friendly resources: Annotations field
    12  
    13  This rule enforces that all declarative-friendly resources have a `map<string,
    14  string> annotations` field, as mandated in [AIP-128][].
    15  
    16  ## Details
    17  
    18  This rule looks at any message with a `google.api.resource` annotation that
    19  includes `style: DECLARATIVE_FRIENDLY`, and complains if the `annotations` field
    20  is missing or if it has any type other than `map<string, string>`.
    21  
    22  ## Examples
    23  
    24  **Incorrect** code for this rule:
    25  
    26  ```proto
    27  // Incorrect.
    28  // The `annotations` field is missing.
    29  message Book {
    30    option (google.api.resource) = {
    31      type: "library.googleapis.com/Book"
    32      pattern: "publishers/{publisher}/books/{book}"
    33      style: DECLARATIVE_FRIENDLY
    34    };
    35  
    36    string name = 1;
    37  }
    38  ```
    39  
    40  ```proto
    41  // Incorrect.
    42  message Book {
    43    option (google.api.resource) = {
    44      type: "library.googleapis.com/Book"
    45      pattern: "publishers/{publisher}/books/{book}"
    46      style: DECLARATIVE_FRIENDLY
    47    };
    48  
    49    string name = 1;
    50    repeated string annotations = 2; // Type should be `map<string, string>`.
    51  }
    52  ```
    53  
    54  **Correct** code for this rule:
    55  
    56  ```proto
    57  // Correct.
    58  message Book {
    59    option (google.api.resource) = {
    60      type: "library.googleapis.com/Book"
    61      pattern: "publishers/{publisher}/books/{book}"
    62      style: DECLARATIVE_FRIENDLY
    63    };
    64  
    65    string name = 1;
    66    map<string, string> annotations = 2;
    67  }
    68  ```
    69  
    70  ## Disabling
    71  
    72  If you need to violate this rule, use a leading comment above the message (if
    73  the `annotations` field is missing) or above the field (if it is the wrong
    74  type). Remember to also include an [aip.dev/not-precedent][] comment explaining
    75  why.
    76  
    77  ```proto
    78  // (-- api-linter: core::0128::resource-annotations-field=disabled
    79  //     aip.dev/not-precedent: We need to do this because reasons. --)
    80  message Book {
    81    option (google.api.resource) = {
    82      type: "library.googleapis.com/Book"
    83      pattern: "publishers/{publisher}/books/{book}"
    84      style: DECLARATIVE_FRIENDLY
    85    };
    86  
    87    string name = 1;
    88  }
    89  ```
    90  
    91  If you need to violate this rule for an entire file, place the comment at the
    92  top of the file.
