This specification covers an analytical data interchange protocol for mass spectrometric data representation and a software vehicle to affect the transfer of mass spectrometric data between instrument data systems. This specification does not provide for the storage of data acquired simultaneous to and integrated with the mass spectrometric data, but on other detectors. The protocol, which is designed to benefit users of analytical instruments and increase laboratory productivity and efficiency, provides a standardized format for the creation of raw data files, library spectrum files or results files. This file, which has a ".cdf" extension, contains typical header information like instrument, sample, and acquisition method description, followed by raw, library, or processed data. Once data have been written or converted to this protocol, they can be read and processed by software packages that support the protocol. This protocol is intended to perform the following functions: (1) transfer data between various vendors' instrument systems; (2) provide Laboratory Information Management Systems (LIMS) communications; (3) link data to document processing applications; (4) link data to spreadsheet applications, and (5) archive analytical data, or a combination thereof.1.1 This specification covers a standardized format for mass spectrometric data representation and a software vehicle to effect the transfer of mass spectrometric data between instrument data systems. This specification provides a protocol designed to benefit users of analytical instruments and increase laboratory productivity and efficiency.1.2 The protocol in this specification provides a standardized format for the creation of raw data files, library spectrum files or results files. This standard format has the extension “.cdf” (derived from NetCDF). The contents of the file include typical header information like instrument, sample, and acquisition method description, followed by raw, library or processed data. Once data have been written or converted to this protocol, they can be read and processed by software packages that support the protocol.1.3 This specification does not provide for the storage of data acquired simultaneous to and integrated with the mass spectrometric data, but on other detectors; for example attached to the mass spectrometer's liquid or gas chromatographic system. Related Specification E1947 and Guide E1948 describe the storage of 2-dimensional chromatographic data.1.4 The software transfer vehicle used for the protocol in this specification is NetCDF, which was developed by the Unidata Program and is funded by the Division of Atmospheric Sciences of the National Science Foundation.21.5 The protocol in this specification is intended to (1) transfer data between various vendors' instrument systems, (2) provide Laboratory Information Management Systems (LIMS) communications, (3) link data to document processing applications, (4) link data to spreadsheet applications, and (5) archive analytical data, or a combination thereof. The protocol is a consistent, vendor independent data format that facilitates the analytical data interchange for these activities.1.6 The protocol consists of:1.6.1 This specification on mass spectrometric data, which gives the full definitions for each one of the generic mass spectrometric data elements used in implementation of the protocol. It defines the analytical information categories, which are a convenient way for sorting analytical data elements to make them easier to standardize.1.6.2 Guide E2078 on mass spectrometric data, which gives the full details on how to implement the content of the protocol using the public-domain NetCDF data interchange system. It includes a brief introduction to using NetCDF and describes an API (Application Programming Interface) that is intended to be incorporated into application programs to read or write NetCDF files. It is intended for software implementors, not those wanting to understand the definitions of data in a mass spectrometric dataset.1.6.3 NetCDF Users Guide.

7.1 General Coding Guidelines—The NetCDF libraries are supplied to developers as source code. End users receive the libraries in compiled binary form as part of a vendor's application.7.1.1 Developers setting out to write a program to convert their data files to the Mass Spectrometric Data Protocol should consider using the NetCDF utilities ncgen and ncdump. After developers create the NetCDF file they should use the ncdump program to generate the ASCII representation of the data file, and examine it to ensure the data are being correctly put into the file.7.2 Make Files for NetCDF Libraries and Utilities—In general the compilation is straightforward. The make files were modified after they were received from the Unidata Corporation, because they did not compile the first time on PCs. The changes needed to get the Unidata distribution to run on DOS are (1) rename the file MAKEFILE to UNIX.MK, and (2) rename MSOFT.MK to MAKEFILE, and then run NMAKE. The default switches in the Unidata distribution use the switches for the floating point coprocessor and Microsoft Windows options.7.2.1 The protocol kit contains some complete makefile examples for Microsoft C V6.0 running on DOS. The Microsoft C V6.0 compiler manual should be consulted for the exact meaning of the compiler and linker options.7.2.2 The VMS and SunOS compilation instructions are in directories for those operating systems.7.3 NetCDF Library Build Order—The NetCDF libraries must be built in a specific order. The correct order to build the NetCDF directories is:UTILXDRSRCNCDUMPNCGENNCTEST7.3.1 The UTIL and XDR makefiles work as distributed using NMAKE with Microsoft C V6.0.1.1 This guide covers the implementation of the Mass Spectrometric Data Protocol in analytical software applications. Implementation of this protocol requires:1.1.1 Specification E2077, which contains the full set of data definitions. The mass spectrometric data protocol is not based upon any specific implementation; it is designed to be independent of any particular implementation so that implementations can change as technology evolves. The protocol is implemented in categories to speed its acceptance through actual use.1.1.2 Specification E2077 contains a full description of the contents of the data communications protocol, including the analytical information categories with data elements and their attributes for most aspects of mass spectrometric tests.1.2 The analytical information categories are a practical convenience for breaking down the standardization process into smaller, more manageable pieces. It is easier for developers to build consensus and produce working systems based on smaller information sets, without the burden and complexity of the hundreds of data elements contained in all the categories. The categories also assist vendors and end users in using the guide in their computing environments.1.3 The network common data format (NetCDF) data interchange system is the container used to communicate data between applications in a way that is independent of both computer architectures and end-user applications. In essence, it is a special type of application designed for data interchange.1.4 The common data language (CDL) template for mass spectrometry is a language specification of the mass spectrometry dataset being interchanged. With the use of the NetCDF utilities, this human-readable template can be used to generate an equivalent binary file and the software subroutine calls needed for input and output of data in analytical applications.

3.1 Intended Use—Compliance with this guide will allow the sharing of electronic data between contracting parties that is normally done by hard copy. This can only be used when both parties use a database-derived software package to manage their contracts. Specifically, it will:3.1.1 Eliminate the duplication of manual entry of data into each party’s contract administration software package and3.1.2 Allow for wide access of the data to all authorized parties.1.1 This guide provides the database structure of electronic data interchange (EDI) information between ship owner and a shipyard for contract administration. Ship owners (hereinafter referred to as owners) and shipyards may each have unique software programs to manage their respective portions of a ship repair period. There is information that must be exchanged between the parties during the contract period. This guide has been developed to establish common field lengths, names, and types such that the exchanged information can be used directly by the respective software programs without scanning, typing, or redundant keying of information.1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
