We have found during the development of ChemSymphony, http://www.cherwell.com/cherwell/chemsymphony that much of the interest has come from companies wishing to use the product internally and therefore using the cross-platform benefits of Java. The speed of compilers at the present time means that internal use will provide better results than relying on bandwidth issues. The security problems of Java have been discussed at length on a number of forums but there are many built in security issues that make Java a secure web development language. However, I do not believe this will be problem in the future. Now that there are a number of applications in Java from the main software vendors, the issue of security will disappear.

DC should enable the author or creator of a document-like object (DLO) to add metadata to every DLO, because he wants that his DLO, for example the full-text-document about the specific behavior of a mercury compound in the environment, will be retrieved by others 8-), and to allow search engines to index the specific DC-Elements separately to allow a better retrieval. For example, the word "mercury" in a quick-and dirty-search in Altavista would retrieve thousands of documents, some from a company named Mercury Ltd. or from the pop star Freddie Mercury and also some of the metal mercury. Sure, you can combine search words, for example mercury with for example environment. But what is do, if you want to know something about the behavior of a specific mercury compound in the environment. (It is clear, in the moment you would search CA for such a question. 8-) But in the future, when every author of his specific mercury compound has his paper in the web or something similar ?) And now to the theme "classification". Sorry for this long run ! The DC element Subject allows the author to describe the topic of his work in keywords and also in any classification code. In the library area there are some international used classification as DDC, UDC or LoC-Classification. But no "normal" scientific author is willing to use such a classification, because he don't know it ! 8-) You can add the type of the classification codes as qualifiers to the DC element. But that is not the problem, but which classification code should use the chemist. Other subjects have their own, specific, widely known classification scheme, the mathematicians will use the AMS classification, the computer scientists the ACM classification, the physicists the PACS (Physics & Astronomy Classification System). All these are used for the indexing also the specific online databases (Mathematical Revies, Physicvs Abstracts ...). One possibility for the chemist would be the CA Section Codes, but are these specific enough ? Are there other possibilities ? It would be very easy to use this. But makes this sense ? Any commentary is welcome ? Or is this discussion only important from a librarian point of view about the chaos of the internet ? 8-) For our example, the future user of a WWW search engine would search in the "DC-Element-"Subject"-Index for example with the qualifier "CAS-RN" the specific mercury compound and combine it with the qualifier "CAS-Section Code" with one of the CAS section codes 58 or 59. Assumed that the author has added this to the DC-Elements of his DLO and the search engines will use this meta information to build their indexes and to allow a retrieval in these sub-indexes, the future would perhaps get the desired information ! Or not !? 8-) Sorry again for this long message.

New Internet Journal
by Dr Paul Heelis 03 Jan '97

03 Jan '97

Call for papers A new completely on-line journal of science has been launched. The Internet Journal of Science - biological chemistry can be found at http://www.netsci-journal.com/ All aspects of Chemistry are included, but with particular emphasis on studies of biologically important molecules. In addition, the journal would like to promote the application of Computers in chemistry such as Molecular Modelling, Cheminformatics and Bioinformatics. There will be 2 sections to each issue. The Journal This will contain peer reviewed articles, Regular papers. Communications. Reviews, both invited and contributed The Magazine This will contain more topical issues, News and views, comments on current trends Educational articles such as practical experiments, teaching articles, computer applications Software reviews and commercial announcements Student section - this will give both post and under-graduate students the opportunity to write papers The journal will host Electronic conferences on its Web Site. Sincerely, The editor, Dr. Paul F.Heelis, North East Wales Institute, UK p.s. My apologises if you receive this message more than once.

CCL:New Journal - Call for papers

I forward a message first posted to the CCL list (apologies for those on that list). I suspect this may be the first of several such announcements in 1997. In view of Paul Deards' article about CAS abstracting relatively few Internet-only items, I wonder whether the journal noted below will be included by CAS. ================== > >Call for papers > >A new completely on-line journal of science has >been launched.

WebElements - the periodic table on the WWW - new version
by Mark Winter 03 Jan '97

03 Jan '97

Dear colleague This is to announce a new version (2 beta 6) of WebElements, the periodic table on the WWW. and to request feedback. The URL is http://www.shef.ac.uk/~chem/web-elements/ WebElements has undergone a major overhaul to include a frames interface and stylesheets so I'd be particularly pleased to hear from those of you with MicroSoft InterNet Explorer versions that support style sheets. Users who do not use style sheets (currently all NetScape users) should not notice any problems, but do let me know if you do. Users who do not have a frames-capable browser can still use the old version until I manage to produce a non-frames version. All of the many chemical errors that observant users have reported are still there, and the next step is to correct these. I do thank everyone who has taken time to make comments and to point out errors. The main reasons for the new layout were user feedback (over 1500 messages). See - I do listen sometimes! The new layout has considerably smaller files and so should allow better download times from outside the UK. Also, I hope the new layout allows for easier navigation. There are still rough edges in the new layout and I'll fix these when I get back from holiday.

MOTM
by Paul May 02 Jan '97

02 Jan '97

Hi, Happy New Year to everyone on the list! January's Molecule of the Month is now available for your inspection. It's C60, which is appropriate both for the recent Nobel prize connection, and for the fact that it's been provided by Henry's Imperial College MOTM collection (who provided the very first MOTM a year ago). The author is Wyn Locke, and the URL is: http://www.ch.ic.ac.uk/motm/c60.html and it's on the MOTM page at: http://www.bris.ac.uk/Depts/Chemistry/MOTM/motm.htm ----------- Another plea: The MOTM idea seems to have been a great success - at least it's survived a year and the number of MOTMs available on-line is now building into quite a useful resource. But I still need more. I have one more ready for Feb, (plus a few that I've personally written that I'm keeping as spares) - but I don't have *any* MOTMs from sites other than Bristol ready for March onwards. So if you feel like contributing one, please let me know. It only takes a couple of hours to write one, and it can get your web site publicity (the Bristol MOTM page gets as many hits as the entire main Bristol Chemistry Home page...). Regards, ----------------------------------------------------------------------------- Dr Paul May, School of Chemistry, University of Bristol, UK tel: +44 (0)117 9287667, fax: +44 (0)117 9251295 email: paul.may(a)bris.ac.uk WWW: http://www.bris.ac.uk/Depts/Chemistry/staff/pwm.htm ----------------------------------------------------------------------------- ----- chemweb: A list for Chemical Applications of the Internet.
