Our research indicates several effects: 1) Most IMS sites are private, intranet sites. They are used for confidential information that people do not want to share with the general public, or the site is an integral part of an internal business process. This is not a suprising outcome as most business and organizational processes are indeed private. For example, the number of Access databases that are web-enabled are a microscopically small percentage of the overall number of Access databases that can be used via internal networks. It is also surprisingly common for intranet usage to involve a lot of sites. I think that is because there are very many internal applications that involve publication of GIS data with lightweight browsing and it is highly cost effective in such cases to buy a single license for a server and then let everyone use the application via a free browser. I believe the record holder in this area is a company that uses Manifold IMS to do an internal application which is deployed in over 500 sites around the world. They deploy runtime licenses using the 100+ discount schedule so it is cheap for them (only $5000 for 100 licenses or only $25,000 for a deployment of 500 IMS sites). By the way, I doubt you could identify 500 functioning ArcIMS sites even considering ESRI's entire installed ArcIMS base, yet that is only a single Manifold customer. 2) Most IMS sites that are on the Internet are not published URLs. There are several reasons for this: a) They contain private information like those on intranets. b) They use a subscription model to gain access to information. c) The owner does not want to spend bandwidth in an uncontrolled way, either for machine throughput or for the pipe. This makes sense, as publishing just one URL wordlwide can quickly overwhelm a small site. Even towns and other government sites are often run on what is relatively small equipment, such as a single server, and the person responsible for the site does not want to lose services for his local users because people from all over the planet are hitting the site. For example, I know several people who operate community sites and who I have seen participate in georeference.org but who did not respond to this posting. d) The owner does not participate in georeference.org or other forums and simply doesn't bother to advertise the web site broadly. This appears to be a significant factor, as a very small percentage of Manifold users ever even lurk in the forums, let alone post. We do our best to promote the forums but can't seem to get people to participate except for small percentage of what appear to be elite users. We can tell this is a factor from our tech support reporting, as it is clear that numerous people are doing IMS stuff and actually buying development incidents when it would be faster and cheaper for them to simply participate in georeference.org. I suspect part of this is because some people just want to pay for "on-demand," for-sure support and are impatient with the process of posting to a forum and hoping for responses, but being a very cheap person by nature I just don't get it. e) The owner is embarassed about how the web site might be perceived by more expert peers. I have personally received many emails pointing out different IMS sites to me that have been accompanied by a request not to tell anyone else the URL "because it's not yet finished" even though it is running in production mode with ordinary users. f) The operator does not want anyone to know the site has been done with Manifold. Quite often, the costs charged for the creation of a big-time IMS site are high, over $100,000, and the developer does not want anyone to know their cost for the actual IMS software was only a $200 runtime license. Because of the very high cost of legacy GIS and legacy IMS software, clients often expect that a GIS-enabled web site will be expensive and the smart consultant will not argue with them about that. :-) 3) In addition to the above points that have been established through actual marketing research, I'd offer my own intuition that the politics of promotion of non-Manifold IMS sites result in more noise than installations. There are three sub-effects here: a) To move a very small number of units at very high unit prices, legacy vendors must use an advertising and reference-sell business model that almost forces them to puff up their actual results. For all the noise about ArcIMS, for example, there are virtually no bona-fide (that is, real production sites not subsidized in some way by ESRI) ArcIMS sites out there - my guess is there are most a few hundred. It appears that only a minority of ArcIMS licenses sold ever result in real, funcitoning sites. But, every slight possibility of a running ArcIMS site is emphatically merchandised by ESRI. There are also heavily subsidized sites run by various agencies that virtually no one uses. These are best understood as make-work for bureaucrats and not as real sites that make sense as an actual GIS application. Good examples are the various "interoperability demonstrations" of idiot-class OGC "applications" which cost millions to do but ultimately are not used in real life. b) The open source community is notorious for credulous repetition of "toy" sites as part of the politics of convincing itself that people do, indeed, actually use open source in ways that rival Microsoft technology. Every small, even theoretical usage is promoted, but little appears as actual business usage. Note that one of the hallmarks of real usage is that people don't talk about it much because it is not considered so astonishing... it just gets used like any other tool. c) Manifold.net does not advertise, nor do we reference sell. You'll never hear a citation from us pointing to any user. So, for the above reasons there appears to be a relative dearth of public IMS URL's out there. However, if you look at the questions about IMS in georeference.org and in Manifold-L, it's clear that many people are, indeed, using IMS. A further datum useful to those who want to infer things about Manifold's business (which we do not disclose) is to look at the rather heavy development effort spent on IMS items as shown in release notes from 5.00 onwards. Obviously, we would not be making the investment effort in these areas if it was not a very significant part of our business and represented in thousands of customer wishlist items. I write at length because it would indeed be helpful to us if we could talk the community into being more open about IMS usage. :-) If anyone has any suggestions how this could be done, I'd be happy to hear them: don't hesitate to write directly to dar@manifold.net
