Overall description 71: 72: The effort described herein is part of a funded pilot project 73: to investigate integration between the National SMETE Digital Library (NSDL) 74: [1] and the LearningOnline Network with CAPA (LON-CAPA) [2]. 75: 76: 77: NSDL is meant to index and point to services across the "deep web"; 78: there are significantly large archival collections of online multimedia 79: resources available for scholarly study [3]. NSDL attempts to implement a 80: uniform protocol for the searching and service referencing of these resources. 81: This amounts to three steps: searching across metadata, viewing 82: metadata records, and downloading a resource/service. 83: 84: 85: Examples of "services" might include: availability of CD-ROMs/DVDs, 86: interlibrary loan requests, and supplemental paper media. 87: 88: 89: LON-CAPA is meant to deliver online educational resources across a transparent, 90: distributed network of load balancing and instructor collaboration. 91: Course/classroom services and extensive 92: "homework problem" delivery and assessment features are available. 93: LON-CAPA centers around users as the fundamental data object. A user 94: logs in, selects an available role (student, teaching assistant, instructor, 95: course coordinator, or a dozen other choices). This role confers a 96: set of privileges within the system by which the user can then create/complete 97: homework problems, view class statistics, browse or search viewable resources, 98: set up courses, and so on (depending on the available role that a user 99: selects). 100: 101: 102: From the standpoint of NSDL, two things must happen on the gateway: 1) LON-CAPA 103: metadata must be available in a suitable XML format (IMS 104: and/or Dublin core with educational extensions); and 2) LON-CAPA must 105: implement an OAI-compatible harvesting protocol [3]. 106: 107: 108: From the standpoint of LON-CAPA, two things must happen via the gateway: 109: 1) maintaining transparency--all interaction with NSDL is to be seamless 110: and "on-the-fly" from the standpoint of users; and therefore 111: 2) tight integration involving caching and mirroring 112: similar to the Cornell strategy [4] is anticipated. 113: 114: C. Software project constraints 115: 116: Open issues: There remain outstanding issues on user authentication 117: and online usage of academic material--some of which 118: will likely remain open after conclusion of this pilot project. 119: Within these constraints, it is still reasonable to think 120: there are large amounts of users and academic material that 121: are to be legitimately handled between the two systems. 122: A priority of the pilot project is to "explore clear and present 123: specifics of how roads can be built and roadblocks can be removed". 124: 125: 126: Software stability: Both LON-CAPA and NSDL are systems of 127: relatively new usage and development. Therefore, no long-term guarantee 128: can be made as to the stability of the gateway in relation to LON-CAPA 129: and NSDL. Within this constraint, demonstrating a current 130: working solution takes priority over longer-range issues specific to the 131: evolution of either LON-CAPA or NSDL. Thus customization of the gateway server 132: may or may not branch independently away from developing designs associated 133: with LON-CAPA and/or NSDL (especially LON-CAPA since the gateway server 134: will initially be set up as a LON-CAPA library server [1]). 135: 136: 137: Time to completion: This project is estimated to involve 138: 2-3 weeks of "full-time" programming by the two programmers associated 139: with implementation (Fixler & Harrison). In reality, this equates 140: to approximately 100 hours of programming for each programmer and 141: will be distributed over the next couple months (completion by March). 142: 143: </ul> 144: <a name='Information_Description' /> 145: II. Information Description 146: <ul> 147: A. Information content representation 148: 149: The metadata must be compatible. As NSDL and LON-CAPA transmit 150: resource information, there needs to be a translation to/from NSDL's 151: IMS/Dublin Core format to/from LON-CAPA's simpler metadata format (see 152: all three sections of the Appendix at the end of this document). 153: 154: LON-CAPA faces two choices: it can either translate to 155: the Dublin Core format with educational extensions (IEEE) or 156: translate to the exhaustive IMS Core and SEL standard. 157: 158: 159: For this project, the goal is for LON-CAPA to allow access to 160: resources which are available in a 100% online format (in other words, 161: it is not necessary for LON-CAPA to coordinate access to NSDL "services" 162: described in the Introduction). 163: 164: 165: For this project, the goal is to allow NSDL access to LON-CAPA resources 166: of low granularity (see Appendix C). Availability and dissemination 167: of higher granularity resources (such as courses) will be a capability 168: outside the bounds of this project. It will be documented though as to what 169: software location this capability might be introduced. 170: 171: 172: In order for sufficient inter-operation to take place, there needs 173: to be accurate handling of the following metadata values 174: (accuracy involving one-to-one mapping or other repeatable solutions): 175: <ul> 176: <li>copyright/policy</li> 177: <li>owner/author</li> 178: <li>domain/archive</li> 179: <li>resource type (image, html, video clip, etc)</li> 180: <li>keywords (need to be reasonably generated on-the-fly for LON-CAPA)</li> 181: </ul> 182: 183: B. Information flow representation 184: <ul> 185: 1. Data flow 186: 187: Communications "from NSDL to LON-CAPA" occur strictly through the gateway 188: computer via the HTTP protocol (and OAI syntax of HTTP request [3]). 189: 190: 191: Communication "from LON-CAPA to NSDL" occur in two different ways. 192: 1) A mirrored repository of available NSDL metadata and resources is 193: gathered through an HTTP web-crawl (using the OAI syntax [3]). 2) 194: Non-gateway computers in the LON-CAPA network access the gateway through 195: a combination of HTTP requests and a TCP/IP socket layer. 196: 197: 2. Control flow 198: 199: In an ideal world, there might be no need for restricting access to 200: knowledge or resources. And, the pilot project is meant to demonstrate 201: possibilities when a pool of resources are largely accessible. 202: Part of this accessibility means being able to control 203: the instances (however occasional) when resources are to receive 204: special treatment in terms of their distribution. 205: 206: 207: There are to be three control "modules" 208: (software abstract interface locations). One control module negotiates as 209: to whether LON-CAPA mirrors a 210: specific NSDL resource that is available for download. This control module 211: may, for instance, dismiss resources with highly restrictive copyright 212: policies or too great a size. 213: 214: 215: The second control module controls whether or not the NSDL resource is 216: viewable by all LON-CAPA users or a specific group of LON-CAPA users 217: (course coordinators, authors, LON-CAPA users at Ohio University, etc). 218: 219: 220: The third control module operates in the opposite direction (moving 221: information from LON-CAPA to NSDL). This module will support 222: user validation data being sent from NSDL (in other words, synchronized 223: with an OAI request) to LON-CAPA; similar 224: in spirit to other user authentication mechanisms being 225: investigated by SMETE (such as Virginia Tech's V-CARD strategy). 226: 227: 228: There are complex and unforeseeable issues associated with these 229: control mechanisms. The goal of this project is not to create a 230: comprehensive solution in this respect. The goal is to demonstrate 231: that informational control mechanisms can be implemented as need arises. 232: 233: </ul> 234: </ul> 235: <a name='Functional_Description' /> 236: III. Functional Description 237: <ul> 238: A.

Functional description 268: 269: 270: <ul> 271: 1. Processing narrative 272: 273: Two general functionalities are to be supported: LON-CAPA is to act as 274: an OAI server, and NSDL resources are to be available for educational usage. 275: 276: 277: A typical OAI server request proceeds as follows. 278: An internet user visits www.openarchives.org and decides to visit LON-CAPA. 279: He is presented with a web interface screen to search all of the open 280: LON-CAPA archives. He is thus carrying out the function: 281: NSDL->search_against_LONCAPAgateway. The gateway receives his search 282: request and invokes the function GATEWAY->search_against_LONCAPAnetwork. 283: This function contacts all of the LON-CAPA library server, thereby 284: enacting a network-distributed function of LONCAPA->answer_search_request. 285: Finally, the user is able view the results in NSDL appropriate 286: metadata format: NSDL->view_LONCAPAgateway_results. 287: 288: 289: Going in the other direction, a typical LON-CAPA server request proceeds as 290: follows. A user visits a LON-CAPA access server and makes a search request; 291: all the LON-CAPA library servers are contacted including the gateway, thus 292: LONCAPA->search_or_browse_against_NSDLgateway. The gateway computer 293: then proceeds to search the NSDL network, but by using a pre-compiled 294: mirror copy of NSDL contents. Thus two functions are needed: 295: GATEWAY->search_NSDLnetwork and GATEWAY->reference_NSDLmirror. 296: Results are returned and are to be viewed; three functions are involved 297: in this: LONCAPA->view_NSDLgateway_results, GATEWAY->view_NSDLnetwork_results, 298: and again, GATEWAY->reference_NSDLmirror. A user selects a resource to 299: access and three functions are involved: LONCAPA->access_NSDLgateway_resource, 300: GATEWAY->access_NSDLnetwork_resource, and GATEWAY->reference_NSDLmirror 301: 302: 303: The GATEWAY->reference_NSDLmirror requires a mirror copy of NSDL. 304: A mirror requires three web crawling 305: functions to, on periodic and automatic basis, 306: list archive contents, look at metadata, and retrieve resources: 307: NSDL->answer_list_records_request, 308: NSDL->answer_metadata_record_request, 309: and NSDL->answer_resource_request. 310: 311: 2. Restrictions/limitations 312: 313: The gateway server will have LON-CAPA software, and NSDL OAI server software. 314: When possible, these software packages and protocols are to be treated as 315: black boxes which are not to be re-engineered. By limiting the 316: re-engineering of LON-CAPA and NSDL OAI components, we allow for further 317: development of all three systems (LON-CAPA, OAI, and gateway) without 318: interfering dependencies. 319: 320: 321: In the functional partitioning shown above, this means most of the software 322: coding will involve the GATEWAY->* components. When gateway-specific changes 323: are inseparably coupled with NSDL->* or LON-CAPA->* software components, it 324: will be documented with the software and communicated to the project 325: supervisors. 326: 327: 3. Performance requirements 328: 329: The gateway should be similar in performance to typical LON-CAPA 330: library servers and NSDL OAI servers. This performance should 331: compare the time involved to: 332: <ul> 333: <li>search for a resource</li> 334: <li>return a list of records</li> 335: <li>transmit metadata in a particular format</li> 336: <li>find and transmit a resource</li> 337: </ul> 338: 339: 340: As a general rule, the performance times should not greatly exceed 341: (>300%) those of regular LON-CAPA library servers and NSDL OAI servers. 342: Lengthy processing times, as attributable to algorithms, are to 343: be communicated to the project supervisors, and the software code location of 344: the algorithms is to be indicated. 345: 346: 347: The gateway is to support both a LON-CAPA interface and a 348: OAI interface (as well as the expected underlying functionalities 349: for those existing software systems). 350: 351: 4. Design constraints 352: 353: The gateway is a standard Linux computer with a static IP on the internet 354: via ethernet. Gateway functionality is to be implemented within this 355: one computer. 356: 357: 5.

Validation and Criteria 535: 536: 537: <ul> 538: A. Performance bounds 539: Hardware bounds: The gateway will operate on one computer 540: with a static IP, ethernet-connected to the internet. The computer 541: will be a reasonably fast workstation with large hard disk capacity 542: (>20 gigabytes). The computer will be Linux compatible and will 543: have an Intel-compatible architecture. 544: Data & Metadata: The data and metadata used will 545: conform to the protocols and existing realities of data and metadata 546: currently present on the archives at www.openarchives.org and 547: the LON-CAPA production cluster. If the data of resources or 548: available metadata exceed the storage capacity of the gateway computer, 549: then the pilot project will be executed on a subset of the NSDL archives 550: with the assumption that the solution is scalable through the introduction 551: and almost duplicate gateway servers and/or hard drives. 552: Network: A continously working internet is assumed. 553: Users: Users are generally considered to be members of the 554: general public when requests are made in either direction (LON-CAPA to NSDL) 555: or (NSDL to LON-CAPA); the software should be useful in this respect provided 556: that sufficient amounts of public/free content exist. 557: User expectations: The searching, viewing, and download of 558: resources should either be virtually instantaneous, limited by 559: network bandwidth, or return the status of activity within 30 seconds. 560: There should not be a labyrinth of interface screens imposed upon 561: instructors or students as they navigate educational material. 562: 563: B. Classes of tests 564: 565: Well-defined software: Are system dependencies reasonably catalogued? 566: Can all the gateway-server-specific files be listed? Is there a CVS 567: source-to-build-to-install procedure? Are any customizations of LON-CAPA 568: files or NSDL OAI server-specific files documented and communicated 569: to others involved in the pilot project? Is testing of gateway services 570: automated so as to support stable software development in the future? 571: 572: 573: LON-CAPA system operability: 574: Do all access handlers appear to be working? (If they are disabled 575: for purposes of non-interrupted gateway processing, is this formalized, 576: modular, and documented?) Specifically: 577: user login, /res space, /res/NSDLDOMAIN/NSDLOWNER space, 578: private construction space, course creation (RAT in the construction space), 579: LaTeX processing, page rendering, metadata viewing, XML parsing, 580: student completion resources (problem, exam, quiz, etc), 581: and logging out. 582: 583: 584: NSDL system operability: Are all features present? Is there a 585: web search interface? Are listing records, retrieving metadata record, 586: and retrieving resource implemented correctly through OAI protocols? 587: 588: 589: Gateway services (specific functions): 590: Are all of the GATEWAY->* functions tested against sample test input 591: and output routines? 592: 593: C. Expected software response 594: 595: A correct solution to creating a gateway should return an answer of 596: "yes" to all the test questions. 597: 598: 599: In addition to careful internal testing of the software by the 600: implementation programmers and supervisors, there is to be an 601: alpha-period of test usage by external personnel familiar with either 602: LON-CAPA or NSDL with a recorded evaluation. 603: 604: D. Special Considerations 605: 606: This is a first-pass effort at a problem. As such, the priority 607: is in actively demonstrating the existence of a reasonable solution 608: more than perfecting the complexities of tangential questions. 609: 610: 611: Therefore, tasks and choices gain importance as they most directly 612: contribute to solving the total problem. For instance, tracking the versions 613: of documents on NSDL could either be a simple series of incrementing numbers 614: as documents change (similar to the LON-CAPA implementation), or 615: could support the complex branching and labelling options of CVS. 616: We would choose simple incrementation since this is the most direct 617: and other features do not relate to the goals of the pilot project. 618: 619: 620: Despite the prioritization of importance, an overarching concern 621: is whether the project augments future capabilities for integration. 622: The functional design and validation scheme are meant, in part, to outline and 623: modularize the software architectural locations for future 624: potentially important features. 625: 626: </ul> 627: <a name='Bibliography' /> 628: VI.
