My task is to determine the proper JCR repository structure for storing of

It seems that binary properties can't be used in such way, so I need to
implement some logic on top of jcr... Could you help?
Yes, binary properties can only be read as a whole (InputStream
returned is read-only) and stored back as a whole (new input stream).
I think the way to go is to copy the existing binary value (note: pseudo-code)
node.getProperty("jcr:data").getBinary().getInputStream()
into either a local file or an in-memory input stream, do your work
there and then finally store the whole stream again
node.setProperty("jcr:data", valueFactory.createBinary(stream))

Thanks, but your solution would be acceptable for small amounts of data,
but in our project we have to deal with big contents, from hundreds of
megabytes to gigabytes, and clients will work remotely
via internet, so they just can't get binary content as a whole, modify
it and upload again.
Is there some other way?
