HowTo: WebDAV properties

WebDAV properties

• Limited support for WebDAV properties are implemented in dCache. WebDAV provides an extensible mechanism for reporting additional meta data about files and directories. These are known as properties and can be queried through the PROPFIND HTTP method - the same mechanism used to list WebDAV collection resources (directories in dCache). Currently only support for checksums, access latency and retention policy is provided.

Get file properties from a single file

curl -u <user>:<passwd> -X PROPFIND -H Depth:0 https://<dcache_webdav_endpoint>/<path>/<file> --data '<?xml version="1.0" encoding="utf-8"?>
        <D:propfind xmlns:D="DAV:">
            <D:prop xmlns:R="http://www.dcache.org/2013/webdav"
                    xmlns:S="http://srm.lbl.gov/StorageResourceManager">
                <R:Checksums/>
                <S:AccessLatency/>
                <S:RetentionPolicy/>
            </D:prop>
        </D:propfind>'

Get file properties from all files in a directory

curl -u <user>:<passwd> -X PROPFIND -H Depth:1 https://<dcache_webdav_endpoint>/<path>/ --data '<?xml version="1.0" encoding="utf-8"?>
        <D:propfind xmlns:D="DAV:">
            <D:prop xmlns:R="http://www.dcache.org/2013/webdav"
                    xmlns:S="http://srm.lbl.gov/StorageResourceManager">
                <R:Checksums/>
                <S:AccessLatency/>
                <S:RetentionPolicy/>
            </D:prop>
        </D:propfind>'

Example: File Checksum via WebDAV

Get checksum from a single file

curl -u <user>:<passwd> -X PROPFIND -H Depth:0 https://<dcache_webdav_endpoint>/<path>/<file> --data '<?xml version="1.0" encoding="utf-8"?>
        <D:propfind xmlns:D="DAV:">
            <D:prop xmlns:R="http://www.dcache.org/2013/webdav"
                    xmlns:S="http://srm.lbl.gov/StorageResourceManager">
                <R:Checksums/>
            </D:prop>
        </D:propfind>'

Get checksum from all files in a directory

curl -u <user>:<passwd> -X PROPFIND -H Depth:1 https://<dcache_webdav_endpoint>/<path>/ --data '<?xml version="1.0" encoding="utf-8"?>
        <D:propfind xmlns:D="DAV:">
            <D:prop xmlns:R="http://www.dcache.org/2013/webdav"
                    xmlns:S="http://srm.lbl.gov/StorageResourceManager">
                <R:Checksums/>
            </D:prop>
        </D:propfind>'
