It will extend SEAD’s publishing tool suite to support Azure as a destination and will use a persistent identification framework (PIDs) to reference datasets at varying granularity. ● SEADTrain project publishes data from AirBox devices for the purposes of creating data science learning modules. We assign a PID to each daily feed from one device, generating daily files per device, per day from the raw readings. For further analysis, this data needs to be queried and subset for specific time ranges. Architecture (workflow)Progress● Strawman Profile○ Sixteen fields are developed for PID Kernel Information, describing PID with human-readable information● Published data○ IU SEAD Discovery page http://d2i-dev.d2i.indiana.edu:8081/iusc-azure-search/search.html○ Sample PID:■ http://hdl.handle.net/11723/test.seadtrain.5e66ce48-236a-4af7-b3e1-8a6700d36abf○ PID Kernel Information{"digitalObjectType":"http://hdl.handle.net/20.5000.347/rdastrawman","digitalObjectLocation":"https://iusc.blob.core.windows.net/0a203465-b853-4556-87c0-ac172fb55674/2017_D239_9E65F90C537D.txt","PID":"http://hdl.handle.net/11723/test.seadtrain.5e66ce48-236a-4af7-b3e1-8a6700d36abf","etag":"2f0733b956baf24c3108fee8e9d767de","RDAKIProfileType":"http://hdl.handle.net/20.5000.347/rdastrawman","lastModified":"2017-08-28T00:00:00Z","creationDate":"2017-08-27T00:00:00Z"}Jetstream Use CaseRichard Higgins, Yu Luo, & Robert McDonaldWhat is Jetstream?● IU operates the Jetstream project amongst others for national community or regional organizations. Jetstream is the National Science Foundations first production cloud for science and will consist of 640 nodes geographically dispersed into 320-node system. https://jetstream-cloud.orgCurrent Jetstream VM Archival ProcessJetstream VM in IUScholarWorks Registry PublishedPreliminary use of straw man profile (1)Property identifier Content format Example Value1 PID Handle http://hdl.handle.net/2022/216262 RDAKIProfileType Handle http://hdl.handle.net/2022/216263 digitalObjectType DCMI Virtual Machine Image4 digitalObjectLocation PURL http://purl.dlib.indiana.edu/iusw/data/2022/21626/pearc17-tutorial5 etag Hash 2f29943275fa5f41c7c5aefbaf8d4382  Preliminary use of straw man profile (2)Property identifier Content format Example Value6 lastModified 2017-08-22T08:20:11Z7 creationDate 2017-06-09T13:46:30Z8 version 10.5967/P9S94Q9 wasDerivedFrom 7f04320f-8a53-407e-b918-6690b584c6c2  10 specializationOf R/RStudio Tutorial11 revisionOf d6c3e12ef9b1dcd4b7d593bde280d13a12 https://use.jetstream-cloud.org/application/images/107RPID Testbed Applied to Jetstream Active VM Management ● Handle System would be a flexible approach of representing Jetstream images and projects.○ Assigning PID for each individual Project and Jetstream Image○ Using Strawman Profile to present the kernel information of Jetstream objects○ Showing human-readable information for users to understand the image and project○ Potentially providing technical metadata for users to rebuild the project and image in other platforms.  Progress● Ingesting the metadata information from IUScholarWorks and Jetstream● Developing a extension profile to support the Strawman Profile for presenting the metadata of projects● Combining the extension profile and Strawman Profile to be a integrated metadata of PID PID Wishlist for Jetstream VMs● Early PID assignment with maximal maschine metadata about the VM● Management of the PID for VM at the active level (Jetstream OpenStack admin interface)● Management of the set of PIDs for VM at the archival level with published state Datacite DOI assignment● Search and discovery of RPID testbed for data gathering for published state DOI assignmentCTS URN Use CaseAlison Babeu & Yu LuoCTS URN● The Canonical Text Services (CTS) Protocol defines a URN-based identifier structure for identifying texts and canonically cited passages of texts. ● It also defines a companion CTS Application Programming Interface (API) protocol for a service to retrieve fragments of texts by canonical reference, as expressed by their CTS URNs.● The CTS URN syntax allows expressions of texts and parts of them to be identified as first class and stably identified data objects.● CTS-API allows these URN based identifiers to be resolved into data they represent.CTS URN-A quick example● urn:cts:greekLit:tlg0012.tlg001.perseus-grc1. ● tlg0012 is the textgroup identifier for Homer, defined as author 0012 in classics canon the Thesaurus Linguae Graecae (TLG)● tlg001 is the work identifier for the Iliad also assigned by the TLG● perseus-grc1 stands for a particular edition/version (1920-Oxford-Allen) that has been published and is available as part of the Perseus Digital Library● Identifier has no permanence or semantic meaning outside classics domain, desire PIDs (e.g. Handles) for texts to make them permanently citable and referenceable outside digital classics domainDescription● Handle System with the flexible resolution capabilities is the approach to automatically linking CTS URNs with an instance or instances of the CTS APIs● Four Roles in CTS:○ Centralized Handle System Provider (CHSP) - one or more organizations assuming responsibility for registering and administering Handle prefixes for CTS Namespaces○ Participating CTS Text Publisher (PCTP) - a publisher of CTS URN identified texts who wants their text URNs to be globally resolved by the Handle System○ hdl.handle.net provider (HDL) - the provider of the global hdl.handle.net proxy service○ Non-Participating CTS Text Publisher (NPCTP) - a publisher of CTS URN identified texts who does not want to participate in the centralized solution but wants to publish a Handle for their textProgress● Template Handle and Mapping Rule○ A single Template Handle can be created as a base that will allow any number of extensions to that base to be resolved as full handles, according to a pattern, without each such handle being individually registered.○ Mapping rule provides a function to map the unregistered Handle into a workable URN URL. ● Sample Handle Request○  https://hdl.handle.net/20.500.12042/ctstest|urn:cts:greekLit:tlg0012.tlg002.perseus-grc2:1.1● Mapping result○ https://cts.perseids.org/api/cts/?request=GetPassage&urn=urn:cts:greekLit:tlg0012.tlg002.perseus-grc2:2.1WorkflowSample use caseUAG Goals and ExpectationsRobert McDonaldRPID Testbed UAG Goals and Expectations● Members are expected to attend two meetings over the next year to give feedback to the RPID Team. These will be held in a zoom virtual environment at a convenient time for all US timezones. (Today is the first of these meetings).● Members commit to emailing any feedback or issues while using the RPID tools to rpid-l@list.iu.edu● Members commit to sharing their PID data interest or needs with the RPID Team.● The RPID team is very interested in trying out new use cases so please let us know how we can help you get started...
