Much discussion followed - Ray will provide revised ASN.1 for ComSpec based on this dscussion More discussion followed - then more discussions of variants. Variant set ids will be registered as object ids and will go into standard and be given node on registration tree. A variant set Variant-1 that meets needs currently expressed will be defined. Long discussion of ES-1 A discussion of ranking and dynamic and meta-elements was held. This was felt to be a more general problem that just as defined in ES-1 - issue will be taken to list. Ray (and others) will work to define a standardized schema - this definition will go into standard. rankPlease, hitsPlease,noTagsPlease, and defaultTagType fields of ElementSetNames in ES-1 got deleted ----- End of (a very long) day 1 Day 2 1) more discussion of ES-1 - as an exercise Ray will attempt to pull out functional units from ES-1 2) V3D8 Walkthrough Introductory section on model dropped - integrated into section 3.1 Ray will add a section to the model with a description of the client/server model - this will be posted to the list for discussion A section on Explain will be added to the model section Deinitions of Implementation Id, Version and Name will be put back - people should comment on these on the list Some defnitions were modified and corrected A long discussion of the Any in Id/Authentication was held - comments will be added to the ASN.1 sayying the Any should be replaced by a choice of types one of which will be the ZIG defined format that wil be included in an appendix A discussion about the expandibility of Explain was held - some changes to the ASN.1 will be made to allow extensibility of each record. Ray and a group of people will explore how to do this Ray pointed out other changes from V3D7 The USMARC code list for languages was added to the references In the secton on extended services section the Request-parameter-package field was renamed to Task-specific parameters The comments in the ASN.1 on what the bits mean for protocol version will be put back in The otherinfo field will be put back into the initialize request In Explain Attribuesdetails will be beefed up for things like Scan and Sort People should get Ray comments on Termlists in Explain Section 3.62 was changed so that if the origin does not specify a preferred-record-syntax or the target is unable to apply the specified one the target will return a diagnostic rather than just select one The note in section 3.6.2 was deleted Term in the query has been made a choice with certain tions only available in version 3 Changes to the diagnostics were discussed - prose will be added to explain why DIAG-1 was created and how it is distinguished from the BIB-1 diagnostics BIB-1 diagnostics will not be expanded - all new diagnostics wll come in DIAG-1 - it was pointed out that one of the implications of this was that a version 2 server that wanted to implement some version 3 facility would also have to implement DIAG-1 since there was no other way to return diagnostics for those new facillities It was also pointed out that a verson 3 client would have to understand DIAG-1 since when talking to a version 3 server t couldnt tell what form of diagnostics it would get back 3) Bill Moen discussed his project to create a database of Z39.50 implementatons and asked or feedback - he will make the survey form available electronically 4) Bill talked about the Goverment Information Locator project and discussed the paper he distributed on it 5) Fay Turner gave a tutorial on the ILL protocol - Joe Zeeman talked about his ILL scenario document and gave a presentation on it - Wayne Davison then talked about some activities going on in Europe involving document delivery including the ION, IDEL and GEDI projects 6) This lead into a discussion of the Wibberly paper "using ILL Request PDU for Document Order" - which started a general discusson on document delivery and Z39.50 --- End of day 2 Day 3 1) discussion of interlibrary loan,document delivery and requesting, ILL protocol and relationship to Z39.50 continued Les Wibberley will write up a proposal for an exteded service document delivery along with help from other interested parties and post it to the list. Mark Hinnenbusch will establish a liaison with the ARL group working on document delivery. Lennie Stovel will post the data elements RLG uses in its private document requesting facility to the list. 2) Concatenation and embedding - Ray presented this as a mechanism for delivering more than 1 pdu at a time and discussed some of the requirements that caused this to be thought about - discussion ensued as to how it would be used, what requirements it solved and what problems it created 3) Intermediate results - Lynch discussed his proposal for using additional search info and resource report formats or such thngs as intermedtiate results and conveying posting counts. An additional field will be added to search to convey the type of information wanted conveyed back and forms will be registered so that the origin can provide templates to the target t be filled in with the kind of information the origin wants reported back - part of the intent of this is to allow such things as presents against intermediate result sets 4) Sort - Ray posed the question of what people wanted to sort on and does SortElement work - a combination of schema and element specification will be added to SortElement 5) Simple unstructured text record syntax - Les Wibberley discussed his paper on this and there was a long discussion on this subject - some prose will be added to the standard that describes SUTRS - this will be derived from the characteristics section of Les's paper - also the maximum length of 72 characters per line will be relaxed from a hard maximum to a best effort Other unstructured text formats will be dealt with at the next meeting 6) Proposed extended services - this was a proposal for additional extended services to set parameters on the target - there was a long discussion of this - it will go into draft 9 for further discussion 7) Additonal Extended Service package types- Peter Ryall discussed this paper - Export and Print services will be merged - further comments should go to Peter - further work on this will be taken to the list and changes wlll be made based on comments - then Ray will draft the ASN.1 for these 8) Attributes - Margaret St Pierre discussed attributes needed by WAIS: 1) Free form text 2) Relevance feedback by text and doc id 3) Known item It was decided to add the following attributes to BIB-1: USE attribute of Concept RELATION attribute of Relevance STRUCTURE attributes of free form, doc text, and doc id This will be taken to the list for further discussion 9) Peter Ryall gave a tutorial on URL's and URN's and there was a discussion on how this related to Z39.50 The following documents were given ZIG numbers at the meeting: ZIG 93-400 Z39.50 Register of Implementors (Denenberg) ZIG 93-401 Z39.50 Version 3 Draft 8 (Denenberg) ZIG 93-402 Additional ES Package Types (Ryall) ZIG 93-403 A Database of Z39.50 Implementation: Data Collection, Database Design, and Data Presentation - Project Description (Moen) ZIG 93-404 SUTRS (Simple Unstructured Text Record Suntax) (Wibberly) ZIG 93-405 Using ILL Request PDU for Document Order (Wibberly) ZIG 93-406 Proposed Extended Services (Wibberly) ZIG 93-407 Expanding Research and Development on the NISO Z39.50 Search and retrieval Standard (Moen) ---- end of day 3 (and meeting)
