Eligibility & Conditions of Use

CDS/DL Usernames

Please note that usernames issued for the STFC CrystalWorks server at Daresbury are for the use of STFC CrystalWorks facilities only. They are separate and distinct from any usernames issued for the EPSRC Physical Sciences Data-science Service website at https://www.psds.ac.uk/

CDS/DL usernames are issued to individual users and not to groups. Users are responsible for their own username and the lending of usernames to other parties is not permitted. Users are also responsible for ensuring that their username is not used for industrial or commercial work.

The CDS/DL computer systems are for running the database and ancillary packages only. Users are not permitted to compile, develop or run their own or other code without prior permission from the CDS/DL.

Users' name, contact information and certain accounting information about computer use at Daresbury will be stored on a computer at Daresbury.

Personal data will only be used, where needed, for the running and administering of the CDS/DL. In general no data which can be linked to an identifiable user will be revealed to any third party, but limited information may be passed on to the EPSRC Physical Sciences Data-science Service (PSDS). This is to comply with specific licensing requirements for the CrystalWorks system.

As part of the registration conditions, users will receive occasional broadcast messages providing news of Service developments. These will be sent using the email address "pmpat@stfc.ac.uk"

Downloading data from the CDS/DL

In general downloading of material from databases provided by the CDS/DL is allowed provided it is for academic use. However, global downloads of datasets are specifically forbidden. Downloaded material cannot be used for commercial purposes. In addition downloading may be subject to specific licensing restriction between the relevant database suppliers and the Royal Societ of Chemistry (see specific conditions for the use of CrystalWorks and for the Cambridge Structural Database).

Specific CrystalWorks conditions of use

CrystalWorks has been developed and is maintained by the STFC Scientific Computing Department at Daresbury Laboratory

We provide UK wide academic access to the CrystalWorks system through an agreement with the EPSRC Physical Sciences Data-science Service (PSDS), which is operated by a consortium between the University of Southampton and the STFC.

Please note that the CrystalWorks has been developed and is maintained by the STFC at Daresbury, but is provided under terms of agreement with the PSDS. It is also be made available via the PSDS website

Your CDS/DL username is for the web server on the Daresbury site only. It will not provide access to CrystalWorks and other components available via the PSDS Service website, which employ different access controls.

Access is available to eligible users only. To allow the PSDS to meet their licensing requirements we are required to pass on some information to the PSDS about new users when they register. Information will be limited to your name, department and email address. Information will not be passed on to 3rd parties or used for purposes other than CrystalWorks related support.

Specific Cambridge Structural Database conditions of use

The Cambridge Crystallographic Data Centre (CCDC), who own the copyright of the CSD and the CSD System, make them available to academic users who undertake to abide by the following conditions:

1. The CSD and the CSD System shall not be used in conjunction with any joint or consulting project with any non-academic organisation without written permission of the CCDC. Academic organisations are defined as not-for-profit, or charitable organisations, supported by private, charitable or Government funding, whose staff may freely publish the results of scientific research through the normal academic channels.

2. The CSD and the CSD System (including downloaded data, manuals, results and printed products) shall be used exclusively for the purposes of scientific training and research, which may include research such as, for example, into drug development or drug modifications capable of commercial exploitation. The results of such research may be published through the normal academic channels provided one or more of the appropriate references is quoted:

3. The data held in the CSD or information derived or obtained from, or by the use of, the CSD or the CSD System is not (whether separately or in combination with other material) distributed or otherwise exploited (except through the product of scientific research as aforesaid) on a commercial or for-profit basis whether in printed, photographic, computer readable or other form, without prior written permission from the CCDC. This restriction applies in particular, but not exclusively, to data compilations, educational aids, fragment libraries and software systems.

4. The user does not develop, for distribution, software to interface to the CSD or CSD System or subfiles derived thereof, without prior written permission from the CCDC.

5. The user shall not copy (including indirectly) the CSD or CSD System or the documentation supplied in whole or in part or in any form whatsoever, whether machine readable or not.

6. The user will comply with and abide by the terms of licence of access made between the CCDC and Daresbury Laboratory, a copy of which is available for inspection.

Conditions of access to STFC network & server systems

The STFC Chemical Database Service is part of the Support & Service Programme of the Computational Science and Engineering Department and is based at the STFC Daresbury Laboratory.

Access to the CDS is free of charge to eligible users, but the Service is currently only available to "UK Academics". A UK Academic is defined as someone employed by, or working at a Higher or Further Education Instutute or related Research Institute (e.g. operated by one of the UK Research Councils) within the UK. This includes lecturers, students, post-doc workers, technicians, librarians, information officers, visiting academics for duration of the visit etc.

The STFC CDS at Daresbury shall be used exclusively for academic research or teaching, i.e. non-profit making research and teaching at academic institutions. The results of such research may be freely published through the normal academic channels.

Users of STFC network services are also bound by the Terms and Conditions of the STFC Telecommunications Monitoring and Acceptable Use Policy and by the JANET Acceptable Use Policy. Details are available at the link.

Anyone in breach of the CDS Conditions of Use may be barred from using the CDS/DL and other STFC facilities.
