Giles provides REST endpoints to specific functionality such as uploading or retrieving images. The following sections describe all so far available endpoints, their parameters, and what they return.

Authentication

Token Authentication

For all REST endpoints, a user has to send a valid API token (see here for a description how to get a token) to authenticate. Some endpoints can be used without a token when requesting public files. Below descriptions indicate when an endpoint can be used without a token. In general, there are two ways to send a token: as request parameter or as Authorization header (this is the recommended way).

When sending a token in the header, add the following header field:

Authorization: token your-api-token

When sending a token as request parameter, add the following to your url:

accessToken=your-api-token

Adding Data

Add files to Giles

POST

In theory, you can add any file type you want to Giles. However, only file types supported by Digilib or file types that Giles knows how to convert really make sense. Currently, Giles knows how to convert PDFs to images. Giles is globally configurable in regards to what image type it uses and what DPI when converting PDFs to images (default is tiff/600 dpi). Giles will create one image per PDF page and put all images together into one folder so that you can use Digilib's paginator feature. The original PDF is stored separately outside of Digilib's image folder.

You can add files to Giles by making a POST request to:

/rest/files/upload

You request should be made with a content-type header of:

multipart/form-data

Giles expects the following parameters:

accessToken: an API token that is used to authenticate the uploading user (if possible use the Authorization header instead of this parameter)
access (optional): access policy for uploaded files; possible values are PRIVATE or PUBLIC; default is PRIVATE.
document_type (optional): specifies if uploaded files are several pages of the same document (MULTI_PAGE) or if they should be uploaded as separate documents (SINGLE_PAGE); default is SINGLE_PAGE.
files: the files to be uploaded

A valid request would look something like this:

POST /giles/rest/files/upload HTTP/1.1
Host: giles-host
Authorization: token your-giles-token
Cache-Control: no-cache
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="files"; filename="test.png"
Content-Type: image/png

[content of file]

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="files"; filename="test.pdf"
Content-Type: application/pdf

[content of file]

Giles will respond with an progress id and a url to check the progress of the upload:

{
	"id":"PROGQ3Fm2J",
	"checkUrl":"http://your-giles-org.net/giles/rest/files/upload/check/PROGQ3Fm2J"
}

You can now poll the url provided as 'checkUrl'. As long as the upload hasn't finished yet, you will get a 202 Accepted response with the following response body:

{
	"msg":"Upload in progress. Please check back later.",
	"msgCode":"010"
}

V0.5 As of version v0.5, Giles will also supply the URL of the upload itself (see "Get info about upload" below). Keep in mind, however, that requests to this URL will return incomplete results as long as processing of a file is ongoing. Only the poll URL will indicate when processing has finished.

Once uploading has finished, you will retrieve the complete information as listed below.

Uploads expire after 24 hours or after a server restart. If you request an expired upload or an upload that doesn't exist you will get a 404 response with the following response body:

{
  "errorCode" : "404",
  "errorMsg" : "Upload does not exist."
}
