daviX is used at CERN by several projects, including the ROOT data analysis framework,^{[4] [5]} the File Transfer Services (FTS),^[6] the European Middleware Initiative gfal2 library ^{[7] [8]} or the dynamic storage federation project.^[9]

Feature support

DaviX supports:

• SSL/TLS
• User/Password Authentication
• X.509 Client certificates authentication
• redirection caching
• Multi-Range requests (Vector I/O)
• checksum calculation
• session recycling
• VOMS credential
• Multi-sources via Metalink.
• SOCKS4/5
• S3 and WebDAV Operations

Examples of daviX command line use

to Upload a file to a WebDav repository$ davix-put local_file davs://example.com/folder1/remote_file

to Download a file from a S3 bucket with AWS authentication$ davix-get --s3secretkey A --s3accesskey B s3://bucket1.s3-instance.com/long/path/remote_file local_file

To list a WebDav repository over https$ davix-ls davs://example.com/folder1/folder2/

To list an S3 bucket with AWS authentication$ davix-ls --s3secretkey A --s3accesskey B s3://bucket1.s3-instance.com/

To create a subdirectory over WebDAV$ davix-mkdir davs://example.com/folder1/folder2/folder4

Execute an HTTP PUT request to a RESTful webservice with the content "hello"$ davix-http -X PUT—data "hello" http://example.com/rest/api/service
