  4. COD - Introduction Data are arriving in ever increasing rates. Thus, automated software tools are needed to cope with the growing amount of data, to provide consistent, uniform and accurate information. The following goals are set by COD team: • build automated structure deposition tools; • build a collaboration platform for structure validation and curation; • ensure data quality – uniformity, integrity, and trustworthiness; • make scientific data freely accessible to anyone.

  5. Deposit your data to COD for publication! http://www.crystallography.net/

  6. COD - Automatic data deposition

  7. Expanding the PCOD 2010 update : 898.707 SiO2 entries were added from ZEFSAII zeolite predictions and the contributions from GRINSP increased to 163.520 (silicates, phosphates, sulfates of Al, Ti, V, Ga, Nb, Zr, or zeolites, fluorides, etc). The PCOD is the first database to attain and offer more than one million of CIF entries. Software : a new GRINSP version is now available [3] for parallel computing (for instance using fully the 8 processors of an INTEL core i7). Other data from other prediction computer programs (CASTEP, CERIUS2, CRYSTAL, G42, GULP, USPEX…) are expected, just send them, please.

  8. PCOD Powder P2D2 All powder patterns (> 1 million) were calculated and gathered in the P2D2 (Predicted Powder Diffraction Database [4]), they can be used for search-match purposes with EVA (Bruker), Highscore (Panalytical) and more soon. Trying to solve the zeolite LZ-200 unknown crystal structure by using PCOD/P2D2 and search-match identification techniques [x]

  10. MPOD Material Property Open Database www.materialproperties.org Inspired by the COD, the MPOD aims to collect and make freely available published material properties data, keeping the connection to the structural information. The data is stored in MPOD files that can be searched for and downloaded from the website. Moreover an online view of the datafile formatting tensors into matrices, of the property and publication details are also available.

  11. MPOD Coded Properties The initial set includes mechanical properties, elastic stiffness and compliance, internal friction; electrical properties, resistivity, dielectric permittivity and stiffness, thermodynamic properties, heat capacity, thermal conductivity, diffusivity and expansion; electromechanical properties, piezoelectricity, electrostriction, electromechanical coupling; optical properties; piezooptic and photoelastic properties; superconducting properties, critical fields, penetration and coherence lengths.Properties are reported in mpod files where the original published paper containing the data is cited and structural and experimental information is also given. One mpod file contains information relative to only one publication and one phase.

  12. MPOD Coded Properties As its inspirator, MPOD files use a Starfile syntax used and developed for the Crystallographic Information Files (CIF). For the structural information, available items in the CORE CIF dictionary are used. A dictionary containing new definitions for the material properties has been written according to the Dictionary Definition Language DDL1. However some tricks were adopted to adapt the relatively strict Starfile syntax to allow for multiple entries still avoiding ambiguousness. The value of a property tag is a label. This label is then used in a _loop where the tensorial index and the actual value is given. Units are univocally defined in the dictionary itself. Experimental conditions (temperature, pressure, … ) can also be inserted in the loop.

  16. Acknowledgments The Vilnius COD development group is financed by the Research Council of Lithuania, contract No. MIP-124/2010 We thank Adriana Daškevič and Andrius Merkys for help with software development and data curation. Authors thank to all CIF donators, listed on our Web page, and to numerous anonymous volunteers who help to collect data and keep COD running. The COD Advisory Board thanks commercial supporters for donated hardware and financial support. The MPOD development was partially carried out within the Xmat project (“Combination of X-Ray diffraction and X-Ray Fluorescence techniques in material science”), supported by the Provincia Autonoma di Trento and the European Union in the framework of the Marie Curie COFUND program - Call for proposals 4 - researcher 2009 – Outgoing.

  17. CONCLUSIONS COD server is technically in position to store and serve all structures that are currently solved.COD deposition procedure ensures syntactic correctness and presence of the most essential CIF data. COD and PCOD are constantly expanded to meet more needs of crystallographic community MPOD currently serves the uploaded data. Automatic uploading and checking is Planned and under development. We rely on the help of crystallographic community to add more data and ensure the data correctness! Use and Add more structures and properties to: http://www.crystallography.net/ http://www.materialproperties.org/ THANK YOU !
