This page describes the basic REST API for working with reviews stored in Archie. This API is interfacing with Archie's XML review document store and is therefore also XML based and works on whole reviews (in RM5 format).

A more granular API, where review sections can be accessed individually, is being designed to interface with the new review database. The new API is expected to replace this API at some point.


All endpoints require a secure connection (HTTPS). If a plain HTTP connection is attempted an error status code 403 (forbidden) is returned.

Authentication must be provided as either HTTP Basic authentication or as Bearer authentication using an OAuth 2.0 access token. If authentication is missing an error status code 401 (unauthorized) is returned.

Possible error codes are:

  • 400 (bad request): If there is a problem with syntax of the request.
  • 401 (unauthorized): If authentication is missing or incorrect.
  • 403 (forbidden): If the user is not authorized to access the review, if the connection is not secure, or if the user is denied access for other reasons than authentication. 
  • 404 (not found): If no review with the given ID exists.
  • 409 (conflict): In case of a check in/out conflict, e.g. if a user tries to check out a review that another user has checked out already.
  • 500 (internal server error): In case of an unexpected problem on the server.

For the test version of each endpoint, replace with

Encoding of response

You can specify an Accept header to control the returned encoding, e.g:

Accept: application/xml;charset=iso-8859-1
Accept: application/xml;charset=utf-8

If you don't specify an Accept header you must be able to deal with either encoding.

Getting a review

Returned MIME type is "application/xml". The response body contains the review in XML format.

Last published version using CD number

GET{CD Number}



Last published version using Review ID

GET{Review ID}



Latest version using Review ID

GET{Review ID}/latest



Specific version using Review ID

GET{Review ID}/{Version}



Checking a review out

Returned MIME type is "application/xml".

PUT{Review ID}/latest

The body of the request should be empty.



The response body contains the review in XML format.

Note: this is a PUT request since it is changing the state of the review.

Checking a review in

Returned MIME type is "application/json".

PUT{Review ID}?tag={version description}

The review in XML (RM5) format must be provided in the body of the request.

The response body contains a plain text report from the check-in.



Undoing a check-out

PUT{Review ID}/latest/undo

The body of the request should be empty.

The response body will be empty. 



Getting lists of reviews / searching

The base request for getting a list of reviews is:


This will return all published reviews in Archie, so for most purposes a filter based on XPath or additional query parameters is required.

The response is an XML document listing the key attributes and properties of each review, and a link for accessing the full review, e.g.:

<reviews count="15">
  <review cdNumber="CD002745" groupId="ARI" reviewId="780800041114324239" searchDate="2011-06-27" stage="R" status="A" checkedOut="false">
<link href="" rel="self" type="application/xml"/>
  <title>Amantadine and rimantadine for influenza A in children and the elderly</title>
  <byline>Alves Galvão MG, Rocha Crispino Santos MA, Alves da Cunha AJL</byline>
<group>Acute Respiratory Infections Group</group>
  <review cdNumber="CD000243" groupId="ARI" reviewId="482299081614134252" searchDate="2013-03-20" stage="R" status="A"checkedOut="true">
<link href="" rel="self" type="application/xml"/>
<title>Antibiotics for acute maxillary sinusitis in adults</title>
<byline>Ahovuo-Saloranta A, Rautakorpi U-M, Borisenko OV, Liira H, Williams Jr JW, Mäkelä M</byline>
<group>Acute Respiratory Infections Group</group>

Query parameters

The following query parameters can be used to restrict the search:

  • groupId (e.g. ARI for Acute Respiratory, see Review Group IDs below): Restrict search to reviews belonging to the specified review group. Default is any group.
  • stage (R = full Review, P = Protocol, T = Title): Restrict search by review stage. Default is any stage. T is only relevant in combination with published=false.
  • status (A = Active, W = Withdrawn): Restrict search by status. Default is any status.
  • phase (A=Authoring, E=Editorial): Restrict search by phase. Default is any phase.
  • myRole (e.g. myRole=Author): Restrict search to reviews for which the authenticated user has the given role. Default is that roles are not considered.
  • myPermission (e.g myPermission=write_authoring, see Permission below): Restrict search to reviews for which the authenticated user has the given permission. Default is View permission (view).
  • startSearchDate (format {yyyy-MM-dd}, e.g. startSearchDate=2014-05-31): Restrict search to reviews with a search date on or after the specified date. Default is any date.
  • published (true or false). Default is true, which means that only published reviews are returned. If published=false, titles and unpublished protocols are also returned.
  • issueId (e.g. 2014-1). Limit search to reviews appearing in a specific issue of The Cochrane Library (needs testing).


In addition to query parameters, an XPath or XQuery expression can also be used to restrict the search. 

The base URL is:{count expression | exist expression}

The default is exist, which can be left out.

Example 1, reviews that contain a Summary of Findings table:

Example 2, reviews from the ARI group with more than one Summary of Findings table:>1?groupId=ARI

Example 3, reviews with at least 10 included studies:>=10

Example 4, reviews with at least one forest plot figure (exist is implied):"FOREST_PLOT"%5D

Note:  [ and ] have to be escaped as %5B and %5D.

Example 5, reviews assessed as up-to-date in 2010:"2010"%5D

Searching within a specific review>"1970"%5D

This will return the STUDY elements of the XML only (i.e. not a full review document) where the year is greater than 1970. The returned XML document will include the path of parent elements leading up to the root element (COCHRANE_REVIEW) but any siblings will be excluded, e.g.:
