1 Introduction

SARA (SGML-Aware Retrieval Application) is a client/server software tool allowing a server which holds a central database of texts with SGML mark-up to be queried by remote clients. Key parts of the system are thus:

In section 2 below, we give a formal description of the SARA protocol, that is, the types of message which the server and its clients can interchange. Section 2.32 describes the Corpus Query Language (CQL) used to express queries against the server. Installation instructions for the server program are given in section 3 . Finally, in section 4 we describe a few simple SARA-related tools.

The process by which a SARA index is created is not yet documented here.

A users' manual for the SARA Windows client is included with the BNC Handbook .

The SARA system was developed by Tony Dodd as part of the BNC Project, with additional funding from the British Library Research and Development Department, and from the British Academy.
