  • Title: What is OPeNDAP software? | OPeNDAP
    Descriptive info: QuickStart.. Support.. Documentation.. User Documentation.. Design Documentation.. Movies.. Project Documentation.. Available Clients.. Available Servers.. Workshops Presentations.. Sources of Data.. Mail Lists.. OPeNDAP Wiki.. › What is OPeNDAP software?.. What is OPeNDAP software?.. OPeNDAP has developed a software framework.. that simplifies all aspects of scientific data networking, allowing simple access to remote data.. Local data can be made accessible to remote locations regardless of local storage format by using.. servers.. Existing, familiar data analysis and visualization applications can be transformed into.. clients.. (i.. , applications able to access remote served data).. Take a look at our answer to the question.. "What Will OPeNDAP Do For Me?".. The OPeNDAP Data Access Protocol (DAP) is a protocol.. for requesting and transporting data across the web.. DAP 2.. 0 uses HTTP to frame the requests and responses.. For details on DAP, see.. Data Access Protocol (DAP), version 2.. which is a technical description of the Data Access Protocol.. This was submitted to NASA's Earth Science Data Systems Standards Process Group and has been accepted as a Recommended Standard (submitted on 8/8/2004, accepted 10/8/2007).. The official.. NASA ESE/RFC distribution point for DAP2.. may provide a more up to date version and also has additional documentation regarding NASA/ESE's adoption of DAP2 as a community standard.. OPeNDAP supports.. a community of users..  ...   developing end-to-end systems which can locate, understand, access, and use scientific data.. OPeNDAP has already developed:.. a flexible data model.. a transport protocol.. software frameworks.. C++ and Java implementations of the data model and transport protocol.. a set of DODS servers.. a set of DODS clients.. Not Just Oceanography.. Although the OPeNDAP software was originally designed and developed by oceanographers and computer scientists for oceanographic data (as part of the DODS and NVODS projects), there is nothing in the design of the OPeNDAP software that constrains its use to oceanography.. Indeed, it has been adopted by the High Altitude Observatory community and is being considered by segments of the meteorological and space science communities.. User Application -- DAP Client.. Once a user's data analysis application (or API) is made network-savvy with the OPeNDAP tools, the scope of an application's search for data is extended because remote data becomes as accessible as local data.. A DAP-enabled application can:.. Get any data anywhere on the Internet that is served by a DAP server.. Use data from any DAP server, pretty much regardless of its native format.. Still perform all its original functions for accessing data locally.. The truly remarkable part:.. you don't have to rewrite the code.. to enable many applications to work as a DAP clients..

  • Title: How do I make my data accessible? | OPeNDAP
    Descriptive info: How do I make my data accessible?.. Wed, 05/11/2011 - 08:23 —.. Available OPeNDAP servers are listed on our.. "Available OPeNDAP Servers".. web page.. If your data is in a format for which an OPeNDAP server has already been written, simply.. download the appropriate server.. and install it on your machine.. (See the.. User's Guide.. for details on how to install a server.. ).. If your data is not in a format with an existing server, you have two options.. First, you can describe  ...   use the FreeForm server to make your data available.. The second option would be to write a new server for your data format.. The difficulty of this task would depend on the complexity of your data format.. For developing a server in C++, see the.. Programmer's Guide.. and the.. Programmer's Reference.. and the tutorial.. Writing a Server.. for more information.. For developing a server in Java, see the.. OPeNDAP Java JavaDocs..

  • Title: About Software Downloads | OPeNDAP
    Descriptive info: About Software Downloads.. All Software.. Hyrax.. WCS.. Matlab - loaddap.. IDL Client.. libdap.. Java Library.. OC.. ODC.. Software from other groups.. › Download.. On this page you will find background information about the software we have available for download.. This information includes the public key we use to sign our software, access to the complete archive and information for software developers who use our toolkits about our open software revision system.. We manage several different open-source software packages and you can download either source code or pre-built binaries from here.. Some of these packages have their own pages that you can access using the links at the right; for others use the All Software link.. Package that have their own pages are:.. Our modular data server.. loaddap.. A Matlab client that can read from any OPeNDAP server and import data directly into Matlab.. loaddap for IDL.. An IDL client that can do the same for IDL.. The OPeNDAP Data Connector is a client that can read and produce plots for many different kinds of data.. It is written in Java and runs on Windows, OS/X and Linux.. ,.. , and.. JavaDAP.. Software development toolkits that can be used to build clients and servers using C++, C and Java.. If you don t see what you are after here, check the All Software page.. If it is not there, contact us at support@opendap.. Note that we also maintain a list of.. Software developed by other groups.. that can read from OPeNDAP servers and that there are several other groups that make servers besides us.. OPeNDAP s Public Key.. OPeNDAP s Public Key is available.. here.. We now (November 2007) sign all of our software releases using.. gpg.. and a key created just for this purpose.. public key.. is bound to the email address.. security at opendap.. The address is real in the sense that email sent there will be answered, although we ask that support questions be sent to the.. support at opendap.. address instead.. To verify a particular software package using its digital signature:.. Import the.. public key into your key ring  ...   the clients, servers, et cetera.. Source.. Binary.. Old DODS releases.. By Release.. Nightly Builds.. We run a suite of builds every night.. Each nightly build is created using code checked out from SVN.. Mostly we use the nightly build process on our current release, although some other software, such as the current development code, is also built.. You can see the status of the.. most recent nightly build.. , although we do not run nightly builds on all of our platforms.. Subversion (SVN).. Another way to get source code is to use anonymous access to our SVN repository.. In Spring of 2005 we switched from CVS to SVN.. Our CVS repository required a login for read access as well as write access.. Our SVN repository provides public read-only access without a password or login.. You ll need an account for write-enabled access; email.. webmaster at opendap.. There are several ways that you can get software using svn.. You can use a web browser; visit the URL.. https://scm.. opendap.. org/svn/.. This is a good way to read over source code if you have specific questions about how a particular function has been implemented.. Note that we re currently reorganizing the sources so there is some duplication in the repository.. Email.. opendap-tech.. if you have questions about what s under active development and what s not.. You can use a web browser to view our.. Trac.. web site, which provides a browser-based interface to our svn repository.. You can use a variety of subversion clients to read from the repository.. Generally, you will want to check out source code from the repository s trunk using the URL https://scm.. org/svn/trunk/.. There are many subversion clients available and many plugins for IDEs.. Where to find specific software in the repository.. There are many projects in our.. subversion repository.. , here are some:.. : The C++ DAP2 library.. Java-OPeNDAP.. : The Java DAP library for both clients and Servers.. This is use by both the netcdf-java library and the TDS (both from Unidata).. : A pure C implementation of DAP for clients.. Used by the netcdf C library..
