H5S_source(serverURL, domain, ...)

Arguments

serverURL	a URL for a port for HDF5Server
domain	character string with path to file for HSDS
...	not used

Value

dmains

DataFrame instance with metadata about the content of hsds server

## Not run: 
bigec2 = H5S_source(URL_h5serv()) # h5serv 
bigec2
dsmeta(bigec2)[1:2,]       # two groups
dsmeta(bigec2)[1,2][[1]]   # all dataset candidates in group 1
hsdsCon = H5S_source(URL_hsds()) # hsds server connection
hsdsCon
getReq(hsdsCon)
setPath(hsdsCon,"/home/stvjc/hdf5_mat.h5") -> hsds
fetchDatasets(hsds)     # grab the dataset id of interest
