triplestore - Duplicate triple in RDF, authoritative view? -

-

If triple is twice triple in the store, then what is it (if any) is the official position about this redundancy ?

In addition, should one third be allowed to store twice in the same context twice in the same triple?

I ask this because in rdflib you can store twice (or more) of the same triple. Rdfib.plugin.get ( 'MySQL', store.Store) ( 'rdfstore') config_string = "host = localhost, password = Foo, user = foo, db = foo" rt = s.open (config_string, create = false) If rt! = Store.VALID_STORE: s.open (config_string, create = true) Graph = rdflib.ConjunctiveGraph (s, identifier = rdflib.URIRef ( "urn: UUID: a19f9b78-cc43-4866-b9a1-4b009fe91f52")) rows = graph. For r in the query ("Select ID value? {Id from value}") for r: print r [0], r [1]

and this is the author

import rdflib from rdflib import store = rdflib.plugin.get ('mysql', store.store) ('rdfstore') Config_string = "host = localhost, password = foo, user = foo, db = foo" rt = s.open (config_string, create = false) if rt = store.VALID_STORE: s.open (config_string, create = true) graph = Rdflib.ConjunctiveGraph (identify, recognize Nkrta = rdflib.URIRef ( "urn: UUID: a19f9b78-cc43-4866-b9a1-4b009fe91f52")) Graph.add ((rdflib.URIRef ( "htt P: // localhost / 1000"), rdflib.URIRef ( "http : // localhost # ha "), rdflib.Literal (" 18 ")) graph.commit ()

What this is what I get 

  sbo @ DHCP-045 is 045: ~ / tmp / gd $ dragon ./reader2.py sbo @ DHCP-045 : ~ / Tmp / gd $ dragon ./reader2.py sbo @ DHCP-045: ~ / tmp / gd $ dragon ./writer2.py Sbo @ dhcp-045: ~ / tmp / gd $ python ./reader2.py http : // localhost / 1000 18 sbo @ dhcp-045: ~ / tmp / gd $ python ./writer2.py sbo @ dhcp-045: ~ / Tmp / gd $ python ./read Er2.py http: // localhost / 1000 18 http: // localhost / 1000 18

For me it appears as a bug. A modified version shows me that both the triangles are related to the same context, and in fact there are two triples 

  len: 2 http: // localhost / 1000 18 http: // localhost / 1000 18 (Rdflib.URIRef ('http: // localhost / 1000'), rdflib.URIRef ('http: // localhost # ha'), rdflib.Literal (u'18 '), & lt; graph identifier = cadence: uuid : a19f9b78-cc43-4866-b9a1-4b009fe91f52 (& lt; class 'rdflib.Graph.Graph' & gt;) & gt;) (rdflib.URIRef ( 'http: // localhost / 1000'), rdflib.URIRef ( 'http: // localhost # ha'), rdflib.Literal (u'18 '), & lt; graph identifier = urn: UUID: a19f9b78-cc43-4866-b9a1-4b009fe91f52 (& lt; class' rdflib.Graph .Graph '& gt;) RDF The Yellow Store is a set of triples, so according to one triple definition, can not be present twice, although most RDF stores are actually trades stores (also known as DDets, set of RDF graphs) and in that case, Triple can be displayed many times It is sometimes referred to as references (like mine,) depending on the store. Authorization is actually meant for the user to define what a particular graph name / reference name means.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
