| | 55 | ==== 1) Overview ==== |
| | 56 | |
| | 57 | Format (syntax) [[BR]] |
| | 58 | Goal remains: one data model for GENI [[BR]] |
| | 59 | Assume: transfer format is XML record (file) [[BR]] |
| | 60 | Have example in XML-like format, and schema/types in RelaxNG [[BR]] |
| | 61 | Need: first software to generate (and consume) MDODs [[BR]] |
| | 62 | |
| | 63 | Contents (semantics) [[BR]] |
| | 64 | Few required elements, many optional elements [[BR]] |
| | 65 | To meet use cases in arch document, sec 4.5 [[BR]] |
| | 66 | Want one-for-one mapping to key elements in current tools (started: perfSONAR; GENI rspec) [[BR]] |
| | 67 | |
| | 68 | Point-of-view [[BR]] |
| | 69 | Often global; therefore includes locators for data objects; must be updated as objects are copied, moved [[BR]] |
| | 70 | Sometimes associated; need to understand [[BR]] |
| | 71 | Should we consider: storing all MDODs in global, MI srvc? this becomes a MD object registry [[BR]] |
| | 72 | |
| | 73 | Structure [[BR]] |
| | 74 | identifier(s) [[BR]] |
| | 75 | descriptor(s) [[BR]] |
| | 76 | holder(s) [[BR]] |
| | 77 | |
| | 78 | ==== 2) Use Cases ==== |
| | 79 | Read the following sections of the [http://groups.geni.net/geni/attachment/wiki/GeniInstrumentationandMeasurementsArchitecture/122010i%20GENI-SE-IM-ARCH-1.0.doc Architecture document:] [[BR]] |
| | 80 | |
| | 81 | 4.5 GATHERING, TRANSFERRING AND SHARING MD [[BR]] |
| | 82 | |
| | 83 | 4.5.1 Schema and Provenance of MD [[BR]] |
| | 84 | schema for MD object contained in MDOD [[BR]] |
| | 85 | provenance of MD object contained in MDOD [[BR]] |
| | 86 | |
| | 87 | 4.5.2 Gathering MD into a Slice [[BR]] |
| | 88 | by first holder, the "owner" [[BR]] |
| | 89 | starts MDOD [[BR]] |
| | 90 | as owner, sets sharing policy, disposal policy [[BR]] |
| | 91 | as gatherer, deals with privacy [[BR]] |
| | 92 | |
| | 93 | 4.5.3 Transferring MD between I&M Services in the Same Slice [[BR]] |
| | 94 | holder updates MDOD as transfers MD object between locations [[BR]] |
| | 95 | option: registers MDOD with MI service [[BR]] |
| | 96 | |
| | 97 | 4.5.4 Transferring MD between I&M Services in Different Slices [[BR]] |
| | 98 | e.g., holder 1 to holder 2 [[BR]] |
| | 99 | holder 1 authorizes transfer, sends object and copy of MDOD [[BR]] |
| | 100 | holder 1 records the transfer in their MDOD [[BR]] |
| | 101 | holder 2 accepts MD object and MDOD, and adds their local location to their MDOD [[BR]] |
| | 102 | holder 2 tracks further transfers in their MDOD [[BR]] |
| | 103 | |
| | 104 | 4.5.5 Sharing MD with Others [[BR]] |
| | 105 | e.g., holder 1 offers MD object at a portal, and registers this with MI srvc [[BR]] |
| | 106 | user 7 requests MD object [[BR]] |
| | 107 | holder 1 checks their sharing policy, authorizes transfer, and records the transfer in their MDOD [[BR]] |
| | 108 | |
| | 109 | e.g., holder 1 transfers MD object to DOA srvc [[BR]] |
| | 110 | user 9 requests MD object from DOA srvc [[BR]] |
| | 111 | DOA srvc checks sharing policy in associated MDOD, authorizes transfer, and records the transfer in their MDOD [[BR]] |

| | 120 | See: I&M in Operator's Infrastructure Measurement Slice [[BR]] |
| | 121 | For example: a GENI operator could get resources, setup a long-running measurement slice, and make data available to other operators or even experimenters. [[BR]] |
