   76: <br /><strong>B. Overall description</strong>
   77: <p>
   78: The effort described herein is part of a funded pilot project
   79: to investigate integration between the National SMETE Digital Library (NSDL)
   80: [1] and the LearningOnline Network with CAPA (LON-CAPA) [2].
   81: </p>
   82: <p>
   83: NSDL is meant to index and point to services across the "deep web";
   84: there are significantly large archival collections of online multimedia
   85: resources available for scholarly study [3].  NSDL attempts to implement a
   86: uniform protocol for the searching and service referencing of these resources.
   87: This amounts to three steps: searching across metadata, viewing
   88: metadata records, and downloading a resource/service.
   89: </p>
   90: <p>
   91: Examples of "services" might include: availability of CD-ROMs/DVDs,
   92: interlibrary loan requests, and supplemental paper media.
   93: </p>
   94: <p>
   95: LON-CAPA is meant to deliver online educational resources across a transparent,
   96: distributed network of load balancing and instructor collaboration.
   97: Course/classroom services and extensive
   98: "homework problem" delivery and assessment features are available.
   99: LON-CAPA centers around users as the fundamental data object.  A user
  100: logs in, selects an available role (student, teaching assistant, instructor,
  101: course coordinator, or a dozen other choices).  This role confers a
  102: set of privileges within the system by which the user can then create/complete
  103: homework problems, view class statistics, browse or search viewable resources,
  104: set up courses, and so on (depending on the available role that a user
  105: selects).
  106: </p>
  107: <p>
  108: From the standpoint of NSDL, two things must happen on the gateway: 1) LON-CAPA
  109: metadata must be available in a suitable XML format (IMS
  110: and/or Dublin core with educational extensions); and 2) LON-CAPA must
  111: implement an OAI-compatible harvesting protocol [3].
  112: </p>
  113: <p>
  114: From the standpoint of LON-CAPA, two things must happen via the gateway:
  115: 1) maintaining transparency--all interaction with NSDL is to be seamless
  116: and "on-the-fly" from the standpoint of users; and therefore
  117: 2) tight integration involving caching and mirroring
  118: similar to the Cornell strategy [4] is anticipated.
  119: </p>
  120: <br /><strong>C. Software project constraints</strong>
  121: <p>
  122: <u>Open issues</u>: There remain outstanding issues on user authentication
  123: and online usage of academic material--some of which
  124: will likely remain open after conclusion of this pilot project.
  125: Within these constraints, it is still reasonable to think
  126: there are large amounts of users and academic material that
  127: are to be legitimately handled between the two systems.
  128: A priority of the pilot project is to "explore clear and present
  129: specifics of how roads can be built and roadblocks can be removed".
  130: </p>
  131: <p>
  132: <u>Software stability</u>: Both LON-CAPA and NSDL are systems of
  133: relatively new usage and development.  Therefore, no long-term guarantee
  134: can be made as to the stability of the gateway in relation to LON-CAPA
  135: and NSDL.  Within this constraint, demonstrating a <strong>current</strong>
  136: working solution takes priority over longer-range issues specific to the
  137: evolution of either LON-CAPA or NSDL.  Thus customization of the gateway server
  138: may or may not branch independently away from developing designs associated
  139: with LON-CAPA and/or NSDL (especially LON-CAPA since the gateway server
  140: will initially be set up as a LON-CAPA library server [1]).
  141: </p>
  142: <p>
  143: <u>Time to completion</u>:  This project is estimated to involve
  144: 2-3 weeks of "full-time" programming by the two programmers associated
  145: with implementation (Fixler & Harrison).  In reality, this equates
  146: to approximately 100 hours of programming for each programmer and
  147: will be distributed over the next couple months (completion by March).
  148: </p>
  149: </ul>
  150: <a name='Information_Description' />
  151: <br /><strong>II. Information Description</strong>
  152: <ul>
  153: <br /><strong>A. Information content representation</strong>
  154: <p>
  155: The metadata must be compatible.  As NSDL and LON-CAPA transmit
  156: resource information, there needs to be a translation to/from NSDL's
  157: IMS/Dublin Core format to/from LON-CAPA's simpler metadata format (see
  158: all three sections of the Appendix at the end of this document).
  159: </p>
  160: LON-CAPA faces two choices: it can either translate to
  161: the Dublin Core format with educational extensions (IEEE) or
  162: translate to the exhaustive IMS Core and SEL standard.
  163: </p>
  164: <p>
  165: For this project, the goal is for LON-CAPA to allow access to
  166: resources which are available in a 100% online format (in other words,
  167: it is not necessary for LON-CAPA to coordinate access to NSDL "services"
  168: described in the Introduction).
  169: </p>
  170: <p>
  171: For this project, the goal is to allow NSDL access to LON-CAPA resources
  172: of low granularity (see Appendix C).  Availability and dissemination
  173: of higher granularity resources (such as courses) will be a capability
  174: outside the bounds of this project.  It will be documented though as to what
  175: software location this capability might be introduced.
  176: </p>
  177: <p>
  178: In order for sufficient inter-operation to take place, there needs
  179: to be accurate handling of the following metadata values
  180: (accuracy involving one-to-one mapping or other repeatable solutions):
  181: <ul>
  182: <li>copyright/policy</li>
  183: <li>owner/author</li>
  184: <li>domain/archive</li>
  185: <li>resource type (image, html, video clip, etc)</li>
  186: <li>keywords (need to be reasonably generated on-the-fly for LON-CAPA)</li>
  187: </ul>
  188: </p>
  189: <br /><strong>B. Information flow representation</strong>
  190: <ul>
  191: <br /><strong>1. Data flow</strong>
  192: <p>
  193: Communications "from NSDL to LON-CAPA" occur strictly through the gateway
  194: computer via the HTTP protocol (and OAI syntax of HTTP request [3]).
  195: </p>
  196: <p>
  197: Communication "from LON-CAPA to NSDL" occur in two different ways.
  198: 1) A mirrored repository of available NSDL metadata and resources is 
  199: gathered through an HTTP web-crawl (using the OAI syntax [3]).  2)
  200: Non-gateway computers in the LON-CAPA network access the gateway through
  201: a combination of HTTP requests and a TCP/IP socket layer.
  202: </p>
  203: <br /><strong>2. Control flow</strong>
  204: <p>
  205: In an ideal world, there might be no need for restricting access to
  206: knowledge or resources.  And, the pilot project is meant to demonstrate
  207: possibilities when a pool of resources are largely accessible.
  208: Part of this accessibility means being able to control
  209: the instances (however occasional) when resources are to receive
  210: special treatment in terms of their distribution.
  211: </p>
  212: <p>
  213: There are to be three control "modules"
  214: (software abstract interface locations). One control module negotiates as
  215: to whether LON-CAPA mirrors a
  216: specific NSDL resource that is available for download.  This control module
  217: may, for instance, dismiss resources with highly restrictive copyright
  218: policies or too great a size.
  219: </p>
  220: <p>
  221: The second control module controls whether or not the NSDL resource is
  222: viewable by all LON-CAPA users or a specific group of LON-CAPA users
  223: (course coordinators, authors, LON-CAPA users at Ohio University, etc).
  224: </p>
  225: <p>
  226: The third control module operates in the opposite direction (moving
  227: information from LON-CAPA to NSDL).  This module will support
  228: user validation data being sent from NSDL (in other words, synchronized
  229: with an OAI request) to LON-CAPA; similar
  230: in spirit to other user authentication mechanisms being
  231: investigated by SMETE (such as Virginia Tech's V-CARD strategy).
  232: </p>
  233: <p>
  234: There are complex and unforeseeable issues associated with these
  235: control mechanisms.  The goal of this project is not to create a
  236: comprehensive solution in this respect.  The goal is to demonstrate
  237: that informational control mechanisms can be implemented as need arises.

  273: <br /><strong>B. Functional description</strong>
  274: <p>
  275: </p>
  276: <ul>
  277: <br /><strong>1. Processing narrative</strong>
  278: <p>
  279: Two general functionalities are to be supported: LON-CAPA is to act as
  280: an OAI server, and NSDL resources are to be available for educational usage.
  281: </p>
  282: <p>
  283: A typical OAI server request proceeds as follows.
  284: An internet user visits www.openarchives.org and decides to visit LON-CAPA.
  285: He is presented with a web interface screen to search all of the open
  286: LON-CAPA archives.  He is thus carrying out the function:
  287: NSDL->search_against_LONCAPAgateway.  The gateway receives his search
  288: request and invokes the function GATEWAY->search_against_LONCAPAnetwork.
  289: This function contacts all of the LON-CAPA library server, thereby
  290: enacting a network-distributed function of LONCAPA->answer_search_request.
  291: Finally, the user is able view the results in NSDL appropriate
  292: metadata format: NSDL->view_LONCAPAgateway_results.
  293: </p>
  294: <p>
  295: Going in the other direction, a typical LON-CAPA server request proceeds as
  296: follows.  A user visits a LON-CAPA access server and makes a search request;
  297: all the LON-CAPA library servers are contacted including the gateway, thus
  298: LONCAPA->search_or_browse_against_NSDLgateway.  The gateway computer
  299: then proceeds to search the NSDL network, but by using a pre-compiled
  300: mirror copy of NSDL contents.  Thus two functions are needed:
  301: GATEWAY->search_NSDLnetwork and GATEWAY->reference_NSDLmirror.
  302: Results are returned and are to be viewed; three functions are involved
  303: in this: LONCAPA->view_NSDLgateway_results, GATEWAY->view_NSDLnetwork_results,
  304: and again, GATEWAY->reference_NSDLmirror.  A user selects a resource to
  305: access and three functions are involved: LONCAPA->access_NSDLgateway_resource,
  306: GATEWAY->access_NSDLnetwork_resource, and GATEWAY->reference_NSDLmirror
  307: </p>
  308: <p>
  309: The GATEWAY->reference_NSDLmirror requires a mirror copy of NSDL.
  310: A mirror requires three web crawling
  311: functions to, on periodic and automatic basis,
  312: list archive contents, look at metadata, and retrieve resources:
  313: NSDL->answer_list_records_request,
  314: NSDL->answer_metadata_record_request,
  315: and NSDL->answer_resource_request.
  316: </p>
  317: <br /><strong>2. Restrictions/limitations</strong>
  318: <p>
  319: The gateway server will have LON-CAPA software, and NSDL OAI server software.
  320: When possible, these software packages and protocols are to be treated as
  321: black boxes which are not to be re-engineered.  By limiting the
  322: re-engineering of LON-CAPA and NSDL OAI components, we allow for further
  323: development of all three systems (LON-CAPA, OAI, and gateway) without
  324: interfering dependencies.
  325: </p>
  326: <p>
  327: In the functional partitioning shown above, this means most of the software
  328: coding will involve the GATEWAY->* components.  When gateway-specific changes
  329: are inseparably coupled with NSDL->* or LON-CAPA->* software components, it
  330: will be documented with the software and communicated to the project
  331: supervisors.
  332: </p>
  333: <br /><strong>3. Performance requirements</strong>
  334: <p>
  335: The gateway should be similar in performance to typical LON-CAPA
  336: library servers and NSDL OAI servers.  This performance should
  337: compare the time involved to:
  338: <ul>
  339: <li>search for a resource</li>
  340: <li>return a list of records</li>
  341: <li>transmit metadata in a particular format</li>
  342: <li>find and transmit a resource</li>
  343: </ul>
  344: </p>
  345: <p>
  346: As a general rule, the performance times should not greatly exceed
  347: (&gt;300%) those of regular LON-CAPA library servers and NSDL OAI servers.
  348: Lengthy processing times, as attributable to algorithms, are to
  349: be communicated to the project supervisors, and the software code location of
  350: the algorithms is to be indicated.
  351: </p>
  352: <p>
  353: The gateway is to support both a LON-CAPA interface and a
  354: OAI interface (as well as the expected underlying functionalities
  355: for those existing software systems).
  356: </p>
  357: <br /><strong>4. Design constraints</strong>
  358: <p>
  359: The gateway is a standard Linux computer with a static IP on the internet
  360: via ethernet.  Gateway functionality is to be implemented within this
  361: one computer.

  422: </p>
  423: <br /><strong>2. Design constraints</strong>
  424: <p>
  425: Since there will be no specific design for the control modules,

  487: <ul>
  488: <li><strong><i>periodic (daily) updating</i></strong><br />
  489: This may or may not be daily, but it will be regular (multiple times a month).
  490: Based on the system clock, the gateway server is prompted to begin
  491: updating its internal mirror of NSDL archives
  492: </li>
  493: <li><strong><i>contact OAI server</i></strong><br />
  494: Gateway server checks to see if a listed OAI server
  495: (based on www.openarchives.org) is available for sending requests to
  496: </li>
  497: <li><strong><i>request list of metadata records</i></strong><br />
  498: Gateway server requests a total list of metadata records from the OAI
  499: server

  501: <li><strong><i>request record</i></strong><br />
  502: Gateway server requests the metadata for a specific OAI record
  503: </li>
  504: <li><strong><i>request record</i></strong><br />
  505: Gateway server requests the resource associated with a specific
  506: OAI record.  The resource may not be useable (based on highly
  507: restrictive copyright or service-based nature) in which case this record
  508: DOES NOT EXIST from the standpoint of LON-CAPA.
  509: </li>
  510: <li><strong><i>notify all subscribing access servers of updates</i></strong>
  511: <br />See Appendix, part C.  If a NDSL-related resource is modified,
  512: all LON-CAPA access servers which have accessed this resource in the recent
  513: past are notified and updated.
  514: </li>
  515: <li><strong><i>receive resource request from LON-CAPA network</i></strong>
  516: <br />When LON-CAPA contacts the gateway for an NSDL related resource,
  517: a LON-CAPA compatible response is given.  (It is expected, though not
  518: yet 100% sure, that the
  519: /res/ tree holds the mirrored information in a manner similar to
  520: other LON-CAPA servers -- /res/DOMAIN/OWNER/RESOURCEPATH/RESOURCE[.meta].)
  521: </li>
  522: <li><strong><i>answer request</i></strong><br />
  523: Return a LON-CAPA compatible response</li>
  524: <li><strong><i>receive OAI harvesting request for metadata pattern</i></strong>
  525: <br />The Gateway web server receives an HTTP OAI query pattern.  A
  526: distributed search across the LON-CAPA library servers is implemented.</li>
  527: <li><strong><i>respond with OAI query result (i.e. record list)</i></strong>
  528: <br />A list of records is returned via the Gateway web server (HTTP)</li>
  529: <li><strong><i>receive OAI harvesting request for metadata record or resource
  530: </i></strong>
  531: <br />A specific metadata or data request is received by the gateway web 
  532: server (HTTP)</li>
  533: <li><strong><i>respond with OAI query result (i.e. metadata record or
  534: resource)</i></strong>
  535: <br />A metadata record or resource is returned in an OAI-compatible manner by
  536: the web server (HTTP)</li>
  537: </ul>
  538: </ul>
  539: <a name='Validation' />
  540: <br /><strong>V. Validation and Criteria</strong>
  541: <p>
  542: </p>
  543: <ul>
  544: <br /><strong>A. Performance bounds</strong>
  545: <p><u>Hardware bounds</u>: The gateway will operate on one computer
  546: with a static IP, ethernet-connected to the internet.  The computer
  547: will be a reasonably fast workstation with large hard disk capacity
  548: (>20 gigabytes).  The computer will be Linux compatible and will
  549: have an Intel-compatible architecture.</p>
  550: <p><u>Data &amp; Metadata</u>:  The data and metadata used will
  551: conform to the protocols and existing realities of data and metadata
  552: currently present on the archives at www.openarchives.org and
  553: the LON-CAPA production cluster.  If the data of resources or
  554: available metadata exceed the storage capacity of the gateway computer,
  555: then the pilot project will be executed on a subset of the NSDL archives
  556: with the assumption that the solution is scalable through the introduction
  557: and almost duplicate gateway servers and/or hard drives.</p>
  558: <p><u>Network</u>: A continously working internet is assumed.</p>
  559: <p><u>Users</u>: Users are generally considered to be members of the
  560: general public when requests are made in either direction (LON-CAPA to NSDL)
  561: or (NSDL to LON-CAPA); the software should be useful in this respect provided
  562: that sufficient amounts of public/free content exist.</p>
  563: <p><u>User expectations</u>: The searching, viewing, and download of
  564: resources should either be virtually instantaneous, limited by
  565: network bandwidth, or return the status of activity within 30 seconds.
  566: There should not be a labyrinth of interface screens imposed upon
  567: instructors or students as they navigate educational material.
  568: </p>
  569: <br /><strong>B. Classes of tests</strong>
  570: <p>
  571: <u>Well-defined software:</u>  Are system dependencies reasonably catalogued?
  572: Can all the gateway-server-specific files be listed?  Is there a CVS
  573: source-to-build-to-install procedure?  Are any customizations of LON-CAPA
  574: files or NSDL OAI server-specific files documented and communicated
  575: to others involved in the pilot project?  Is testing of gateway services
  576: automated so as to support stable software development in the future?
  577: </p>
  578: <p>
  579: <u>LON-CAPA system operability:</u>
  580: Do all access handlers appear to be working?  (If they are disabled
  581: for purposes of non-interrupted gateway processing, is this formalized,
  582: modular, and documented?)  Specifically:
  583: user login, /res space, /res/NSDLDOMAIN/NSDLOWNER space,
  584: private construction space, course creation (RAT in the construction space),
  585: LaTeX processing, page rendering, metadata viewing, XML parsing,
  586: student completion resources (problem, exam, quiz, etc),
  587: and logging out.
  588: </p>
  589: <p>
  590: <u>NSDL system operability:</u> Are all features present?  Is there a
  591: web search interface?  Are listing records, retrieving metadata record,
  592: and retrieving resource implemented correctly through OAI protocols?
  593: </p>
  594: <p>
  595: <u>Gateway services (specific functions):</u>
  596: Are all of the GATEWAY->* functions tested against sample test input
  597: and output routines?
  598: </p>
  599: <br /><strong>C. Expected software response</strong>
  600: <p>
  601: A correct solution to creating a gateway should return an answer of
  602: "yes" to all the test questions.
  603: </p>
  604: <p>
  605: In addition to careful internal testing of the software by the
  606: implementation programmers and supervisors, there is to be an
  607: alpha-period of test usage by external personnel familiar with either
  608: LON-CAPA or NSDL with a recorded evaluation.
  609: </p>
  610: <br /><strong>D. Special Considerations</strong>
  611: <p>
  612: This is a first-pass effort at a problem.  As such, the priority
  613: is in actively demonstrating the existence of a reasonable solution
  614: more than perfecting the complexities of tangential questions.
  615: </p>
  616: <p>
  617: Therefore, tasks and choices gain importance as they most directly
  618: contribute to solving the total problem.  For instance, tracking the versions
  619: of documents on NSDL could either be a simple series of incrementing numbers
  620: as documents change (similar to the LON-CAPA implementation), or
  621: could support the complex branching and labelling options of CVS.
  622: We would choose simple incrementation since this is the most direct
  623: and other features do not relate to the goals of the pilot project.
  624: </p>
  625: <p>
  626: Despite the prioritization of importance, an overarching concern
  627: is whether the project augments future capabilities for integration.
  628: The functional design and validation scheme are meant, in part, to outline and
  629: modularize the software architectural locations for future
  630: potentially important features.
