XPort: “X-ray Portal”, funded (for one year) by the DOE as part of the Internet-2 initiative. The funding for all Internet-2 projects was terminated early in the second year. The goal of the XPort project was to utilize grid-accessible hardware to create an X-ray portal. The idea was to utilize video cameras and communication systems to allow a remote user to “participate” in an experiment. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
Reciprocal Net: The Reciprocal Net was funded as a part of the National Science Foundation Division of Undergraduate Education National Science Digital Library (NSDL). The main thrust of the Reciprocal Net was to create a distributed molecular database that placed servers in crystallography laboratories throughout the United States and the world.

CIMA: Common Instrument Middleware Architecture (CIMA) is a part of the National Science Foundation Middleware Initiative (NMI). The Common Instrument Middleware Architecture (CIMA) project, supported by the NMI, is aimed at "Grid enabling" instruments as real-time data sources to improve accessibility of instruments and to facilitate their integration into the Grid. CIMA middleware is based on current Grid implementation standards and accessible through platform independent standards such as the Open Grid Services Architecture (OGSA) and the Common Component Architecture (CCA). Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
Crystal Grid Framework: The Crystal Grid Framework is funded by the Science and Engineering Information Integration program in the Division of Information & Intelligent Systems of the National Science Foundation The CrystalGrid Framework (CGF) project will investigate issues in acquisition, transport, and curation of data over the entire data space of the field of X-ray crystallography, and within that context, methods for managing wide heterogeneity in data representations, formats, and containers, taking into account the realities of multiple administrative domains and diverse instruments and equipment. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
Why “Grid Enable” (or “Cyber-enhance) X-ray Crystallography? • “Cyber-enhancement” will allow: • Remote access (and monitoring) during data collection • Near real-time access to data using simple web browsers • Development of standards for data formatting and archiving • Remote collaboration and assistance • A repository for raw crystallographic data that is now discarded • Access to crystallographic data that would otherwise be lost • Education and public outreach Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
The Reciprocal Net is the most mature of these projects. Currently, there are eighteen laboratories involved including the ChemMatCARS beamline at Argonne National Laboratory, the National Crystallographic Service of the UK, the University of Sydney (Australia), Los Alamos National Laboratory, and thirteen university laboratories in the US and Canada. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
The Reciprocal Net is the most mature of these projects. Each laboratory maintains its own server and controls the access to all data stored on that server. There is no “master” administrator. The JaMM applets for viewing the molecules allows the non-technical users to perform all the necessary graphics using only a web browser. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
The Reciprocal Net is the most mature of these projects. For the “end user” the graphics capability are the most desired feature. The chemist can easily generate publication quality graphics without having to learn how to use complex programs. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
The Reciprocal Net is the most mature of these projects. The “Common Molecules” server, with about 600 molecules receives about 750,000 hits per month (about 18,000 unique visitors). The site was selected as one of the top science and engineering sites on the web by Scientific American for 2004. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
The Reciprocal Net is the most mature of these projects. Using the same underlying database, the user view is designed for general education use. The user still has all the graphics capability of the “research” molecules. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
CIMA The CIMA project builds on the visualization and monitoring hardware initially implemented in the DOE XPort project. The primary difference is the data collection and archiving functions. Not only are the “raw” CCD frames collected, but environmental metadata, crystal images, etc. are harvested in a way that allows the user to monitor the progress of the data. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
CIMA The data are stored on an institutional repository to insure availability and security. Current or completed data sets can be examined remotely using web services. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
CIMA The data can be examined frame-by-frame prior to processing, and images can be combined to create mpeg files of the complete experiment.. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
A primary CIMA requirement is that the original instrument should not be modified in any way (or at least minimally) University maintained systems(Data Capacitor) Instrument proxy-box Instrument and local sensors University maintained Mass Storage systems(HPSS) Chemical Informatics and Cyberinfrastructure Collaboratory - 2005

Remote collaboration and assistance Several techniques are being explored with Polycom videoconferencing being the current preferred solution. The Polycom unit is relatively inexpensive and can be readily moved to a classroom or office. The Polycom unit in the IUMSC uses auxiliary video input signals to show the crystal images. In a worst case scenario it would be possible to simply phone the laboratory and use the video images from the web pages. The smaller version of the Polycom, the ViaVideo, is also sufficient for many collaborations and easier to set up. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
Remote collaboration and assistance The IUMSC has over 15 video cameras that can monitor any phase of the crystallography experiment. Cameras can be easily selected and controlled using a web browser. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005

Modes of collaboration The CIMA crystallography portal is designed for a diverse matrix of users and instruments: Data storage Facilities Instrument In Lab 1 Observers Web Interface Local Users Remote Users Tele-colla-boration Instrument In Lab 2 Local Users Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
Education and public outreach One use of the current system was been the development of a “virtual crystallography” laboratory. A group of students and faculty from Ball State University remotely participated in the entire process of determining a molecular structure. They were able to observe mounting a crystal; collection of data; solution of the structure; and examination of results on the Reciprocal Net. The response was positive and we are currently working with 12 other Indiana institutions to provide the “virtual crystallography” exercise to advanced inorganic and other classes.

IUScholarWorks: Provides an institutional repository for indexable, searchable reports that tie the final crystallographic results to the raw data. Chemical Informatics and Cyberinfrastructure Collaboratory - 2005
