Specifications, Validators and Tools

Who should be reading this?

The following chapters and tools are written by developers and for developers. If you're a project manager, then please assign developer(s) from your team to keep track of the changes in these specifications.

Developers chosen by the partners SHOULD:

  • Understand Git and be able to work with it fluently, in order to continually keep track and review all the changes to the specifications.

  • Have significant experience with XML namespaces, and XML Schema language.

Integration with other EU projects

We are designing our Registry in a way that should allow it to be of use in other EU projects too. If you are developing such a project, consider using our Registry Service by hosting the Discovery Manifest file compatible with our specifications. It's pretty straightforward and it should give you a head start (as you won't need to implement a Registry of your own).

We are aiming for our Registry and Discovery API to become common underlying parts of all similar projects focused on higher education in Europe. They are designed to be extendible and can be used to describe all kinds of APIs (even if some of these APIs clash together, by serving similar purpose in a different manner).

What is EWP?

Erasmus Without Paper (EWP) project aims to ease exchanging data on student mobility between computer systems in different countries (more information here). In order to make use of EWP, you will need to implement a subset of its APIs.

There are many APIs already present, and each partner will be allowed to choose which of them he wants to implement (which allows you to start early, and then expand to other scopes you want to participate in, step by step). Each such API is documented separately.

Issue tracker

You can find all unresolved EWP issues here (if you get 404 error, then sign in to GitHub first). If you want to browse only for the issues regarding one particular project, then go to the Issues tab on that project's GitHub page (these are quite mixed up though). You may also be interested in the available search qualifiers.

Documents and specifications

version < 1.0.0 (status labels used for draft documents)

  • DRAFT - working on it;
  • REVIEW RECOMMENDED - still not a final version, but initial review is recommended;
  • PENDING APPROVAL - waiting for the partners to officially accept the document.

Note, that discontinued drafts are simply removed from the index of documents below. That's why there's no label for them.

version >= 1.0.0 (status labels used for released documents)

  • LATEST RELEASE - the latest accepted version of the document;
  • OBSOLETE - might still be in use, but it's recommended to use a newer version;
  • DEPRECATED - might still be in use, but should be replaced with other API;
  • DISCONTINUED - might have been used in the past, but is no longer; do not use it.

Libraries and tools



Echo API Validator

This tool helps you to determine if your implementation meets the basic EWP standards (in particular, all its security requirements).

Echo API has been designed to serve two purposes: (a) to make developers aware of the specific security features required by EWP, and (b) to allow us to run automated tests on all existing implementations (thus reducing the risk of security misconfiguration). You will need to implement this API first, and make sure it is connected to our developer network.

Select Echo API instance to run validation on:

Version 1 only:

Please note, that this validates Version 1 implementations of the Echo API only. Version 1 is now DEPRECATED, and you SHOULD implement Version 2 instead. You cannot use this validator to test Version 2 of the Echo API. We are planning to implement support for Version 2 in the future, but you SHOULD NOT expect, nor wait for this to happen. Make use of Echo API specification instead.

XML Schema Validator

This tool will help you with writing EWP XML documents. For example, you can paste the contents of your Manifest file here before you upload it onto your production site. You should be able to validate any XML document described in any RELEASED specification described above (and most of the OBSOLETE ones).

Note, that it will validate against the schema only. Even if such validation succeeds, your file may still be invalid (if, for example, you didn't adhere to the guidelines described in <xs:documentation> elements included in the XSD files).
