General notes

For the basic annotation CRUD handling, AnnoRepo has a /w3c/ endpoint that implements part of the W3C Web Annotation Protocol
As the protocol does not specify how to create, update or delete annotation containers, AnnoRep implements endpoints for that in a way similar to that used by elucidate

• The following requests expect the annorepo server to be running locally at http://localhost:8080/

• Features marked (experimental) are likely to change in an upcoming release.

• Endpoints marked with 🔒 require authentication if the server was started with authentication enabled (withAuthentication: true in /about ).

• Authentication is done by adding an Authorization header to the request:

  Authorization: Bearer {apiKey}
  

• Endpoints marked with 🔒🔒 are only available when the server was started with authentication enabled, and require root authentication.

• {variable}s in the Request parts need to be substituted with the appropriate value.

• Gzip compression is enabled by default:
  • Add the header Content-Encoding: gzip when sending gzip-compressed data.
  • Add the header Accept-Encoding: gzip to receive the data gzip-compressed. (Data smaller than 256 bytes will not be compressed)

Annotation Containers

Creating an annotation container (🔒)

If the annorepo instance has authorization enabled, the user creating a container will automatically get ADMIN rights to that container. (see Container Users)

Use a slug header to choose your own container name. If a container with the same name already exists, AnnoRepo will generate a new one. Setting readOnlyForAnonymousUsers to true will give anonymous users (those without an api-key) read-only access to the public endpoints. Default is false

Deleting an annotation container (🔒)

If the container contains annotations, the delete will return a 400 Bad Request with a warning to delete the annotations first.

You can override this by adding ?force=true to the request.

The If-Match header must contain the ETag of the container.

Request

DELETE http://localhost:8080/w3c/{containerName}/ HTTP/1.1

If-Match: "{etag}"

Response

HTTP/1.1 204 No Content

Changing the read-only for anonymous users setting for an annotation container (🔒)

Send true to the endpoint to make the container read-only for anonymous users. Send false to the endpoint to lock the container for anonymous users.

Request

PUT http://localhost:8080/services/{containerName}/settings/isReadOnlyForAnonymous HTTP/1.1

Content-Type: application/json

true

Response

HTTP/1.1 200 OK

Annotations

Adding an annotation to a given annotation container (🔒)

As with the container creation, you can let annorepo pick the annotation name:

Request

POST http://localhost:8080/w3c/{containerName}/ HTTP/1.1

Accept: application/ld+json; profile="http://www.w3.org/ns/anno.jsonld"
Content-Type: application/ld+json; profile="http://www.w3.org/ns/anno.jsonld"

  "type": "Annotation",
  "body": {
    "type": "TextualBody",
    "value": "I like this page!"
  },

Querying a container

Create a query (🔒) (experimental)

Request

POST http://localhost:8080/services/{containerName}/search HTTP/1.1

{
  "purpose": "tagging",
  "body.type": {
    ":isNotIn": [
      "Line",
      "Page"
      ]
  },
  ":overlapsWithTextAnchorRange": {
    "start": 12,
    "end": 134,
    "source": "https://textrepo.republic-caf.diginfra.org/api/rest/versions/42df1275-81cd-489c-b28c-345780c3889b/contents"
  }
}

This request body (the query) consists of three parts:

• a field query, which in this case describes we want annotations that have the value tagging in the root purpose field.
• an extended field query, which in this case has the query operator :isNotIn
• a call to the custom query function :overlapsWithTextAnchorRange with source, start and end parameters.

This query will return only those annotations in my-container that match with all three sub-queries.

In general, a query must consist of at least 1 field query, extended field query or query function call, and the returned annotations must match with all the sub-queries.

field names

• field names are case-sensitive
• values are case-sensitive, and must match the entire field value.

example: "purpose": "tag" will not match with "purpose": "tagging" or "Purpose": "tag"

• use . to indicate the hierarchy depth of the field.

example: given this body:

{
  "body": [
    {
      "type": "Object",
      "metadata": {
        "height": 12,
        "width": 10,
        "color": "yellow"
      }
    },
    {
      "type": "Text",
      "value": "Hello, World!"
    }
  ]
}

This json contains the queryable fields:

• body.type
• body.metadata.height
• body.metadata.width
• body.metadata.color
• body.value

Use the fields endpoint to see the fields available in the container.

(simple) field query

This matches the given field with the given value.
A value can be a:

• string ("value")
• number (42, 3.14159265358979323846, 6e23)
• boolean (true, false)

extended field query

In an extended field query you can use one of the following query operators:

• := to indicate the field value should be the given value:
  example: "body.type": { ":=": "Object" } will return those annotations where body.type has the value Object.

• :!= to indicate the field value should not be the given value:
  example: "target.type": { ":!=": "Image" } will return those annotations where no body.type has the value Line.

• :< to indicate the field value should be less than the given value:
  example: "body.metadata.offset": { ":<": 100 } will return those annotations where body.metadata.offset has a value less than 100.

• :<= to indicate the field value should be less than or equal to the given value: example: "target.selector.beginCharOffset": { ":<=": 10 } will return those annotations where target.selector.beginCharOffset has a value less than or equal to 10.

• :> to indicate the field value should be greater than the given value:
  example: "body.metadata.offset": { ":>": 100 } will return those annotations where body.metadata.offset has a value greater than 100.

• :>= to indicate the field value should be greater than or equal to the given value: example: "target.selector.beginCharOffset": { ":>=": 10 } will return those annotations where target.selector.beginCharOffset has a value greater than or equal to 10.

• :isIn to indicate the field value should be one of the values in the given list:
  example: "body.type": { ":isIn": [ "Object", "Text"] } will return those annotations where body.type is either Object or Text

• :isNotIn to indicate the field value should not match with any of the values in the given list:
  example: "target.type": { ":isNotIn": [ "Image", "Text"] } will return those annotations that have no target.type with values Image or Text

query function call

A query function in AnnoRepo is a pre-programmed combination of simple and extended field queries, and can be called with a parameter map. The query function

Currently, the following query functions are available:

• :isWithinTextAnchorRange (parameters: source, start, end)
  This function will return those annotations that fall within the TextAnchorRange defined by the source uri and the start and end TextAnchor numbers.

• :overlapsWithTextAnchorRange (parameters: source, start, end)
  This function will return those annotations that overlap with the TextAnchorRange defined by the source uri and the start and end TextAnchor numbers.

Querying globally

To query all the containers the user has read-access to, use the /global/search endpoint in a similar way as querying a specific container.

Create a global query (🔒) (experimental)

Request

POST http://localhost:8080/global/search HTTP/1.1

{
  "purpose": "identifying"
}

Response

HTTP/1.1 201 Created
Location: http://localhost:8080/global/search/73f62348-7dcc-4d13-9748-fcb8f5a8a367
Link: <http://localhost:8080/global/search/73f62348-7dcc-4d13-9748-fcb8f5a8a367/status>; rel="status"
Content-Type: application/json

{
  "query" : {
    "purpose": "identifying"
  },
  "startedAt" : "2023-05-02T12:49:32",
  "finishedAt" : null,
  "expiresAfter" : null,
  "state" : "RUNNING",
  "containersSearched" : 0,
  "totalContainersToSearch" : 11,
  "hitsFoundSoFar" : 0,
  "processingTimeInMillis" : 2
}

Creating the global query returns its location in the Location header. The body returned is a representation of the status of the search, with the fields:

• query: the query used
• startedAt: the time the search was started
• finishedAt: the time the search was finished, or null if the search hasn’t finished yet.
• expiresAfter: the time after which the search results may not be available anymore, or null if the search hasn’t finished yet.
• state: the state of the search; this can be:
  • CREATED: the search was created, but not started yet
  • RUNNING: the search is applying the query to all relevant containers
  • DONE: the search is finished
• containersSearched: the number of containers that have been searched so far.
• totalContainersToSearch: the number of containers to search in total.
• hitsFoundSoFar: the number of annotations found so far.
• processingTimeInMillis: The number of milliseconds that the search has run.

Indexes

When some fields are queried often, creating an index on that field will speed up the querying.

Add index (🔒)

Request

PUT http://localhost:8080/services/{containerName}/indexes/{fieldName}/{indexType} HTTP/1.1

(no body required)

Available options for indexType:

• hashed - for fields used in simple field queries or the extended field queries: :=, :!=, :isIn, :notIn
• ascending - for fields used in extended field queries :<, :<=, :>, :>=
• descending - for fields used in extended field queries :<, :<=, :>, :>=

Response

HTTP/1.1 201 CREATED
Location: http://localhost:8080/services/my-container/indexes/body.type/hashed
Link: <http://localhost:8080/services/my-container/indexes/body.type/hashed/status>; rel="status"
Content-Type: application/json

{
    "startedAt": "2023-07-05T18:11:04",
    "finishedAt": null,
    "expiresAfter": null,
    "state": "RUNNING",
    "errors": [

    ],
    "processingTimeInMillis": 1
}

As creating an index for a container that already has a lot of annotations might take a while, this endpoint starts the index creation in the background, and returns the current status of the index creation in the body, and the url where to see an up-to-date status in a Link header.

Container Users

These endpoints are only functional on annorepo servers that have authentication enabled.

Only users with admin rights to the given container (and the root user) can use these endpoints.

Users that have been previously added via the add users endpoint can be added to the given container, with one of these roles:

• GUEST -> user has read-only access to the container
• EDITOR -> user can read and write to the container, but cannot add or delete container users
• ADMIN -> user can read and write to the container, and add or delete users for this container

Miscellaneous

Get Annotation Field Count (🔒)

When composing a search query, it helps to know what annotation fields you can search on, and also how many annotations contain that field. The services/fields endpoint serves this purpose: it will return a map/dictionary of all the annotation fields available in the given container, plus the number of annotations that field is used in.

Request

GET http://localhost:8080/services/{containerName}/fields HTTP/1.1

Response

HTTP/1.1 200 OK

Content-Type: application/json
Vary: Accept-Encoding

{
  "body.id" : 1,
  "body.type" : 15,
  "body.value" : 15,
  "target" : 15,
  "type" : 15
}

This response, for example, indicates there are 15 annotations in my-container with a target field, and only 1 with a body.id field.

---
