Kingsley, I am trying to respond to your factual arguments inline. But let me first point out that the central problem for me is exactly what Mike pointed out: "In your enthusiasm and cheerleading you as often turn people off as inspire them. You too frequently take it upon yourself to "speak for the community". Semgel is a nice contribution being contributed by a new, enthusiastic contributor. I think this is to be applauded, not lectured or scolded. Semgel is certainly as much on topic as most of the posts to this forum."
The message you should hear is that many people are frustrated by the way the discussions in this forum are carried out and have already stopped contributing or even reading. And this is a very bad development for a community. The topic we are discussing right now is only a symptom. Please think about it.

Indeed. This is my right as much as yours is to claim the opposite. My claim is founded in the many discussions I have when going to the CTOs of *real* companies (big ones, outside the research business) out there and trying to convince them that they should build on Semantic Web technologies (because I believe they are superior). Believe me, even though I strongly believe in the technology, this is a very tough job without a good reference example that convinces them they will save X millions of Euros or improve the life or their employees or the society in the short- to medium term. Random sample answer from this week (I could bring many): "So this Linked Data is a possibility for data integration. Tell me, why should I convince my engineers to throw away their proven integration solutions? Why is Linked Data so superior to existing solutions? Where is it already in enterprise use?". The big datasets always sold as a success story in the Linked Data Cloud are largely irrelevant to businesses: - they are mostly dealing with internal data (projects, people, CRM, ERP, documents, CMS, …) where you won't find information in the LD cloud anyways - they do not trust "just some" data from the Internet to build multi-million business decisions on top - they find the data in the cloud too messy (as an example: try finding country codes on DBPedia …) and too unreliable (most servers do not respond in sufficient time) Mike has actually assembled some very nice blog posts on related topics: - http://www.mkbergman.com/917/practical-p-p-p-problems-with-linked-data/ - http://www.mkbergman.com/859/seven-pillars-of-the-open-semantic-enterprise/ > >> And if you look at the recent troubles with Semantic Web business models you >> see the consequences. > > Please clarify what you mean as that statement is quite unclear.

I was referring to the recent bankruptcy of Ontoprise and the fact that Talis is reducing its Linked Data involvement, essentially shutting down their "we help you publish Linked Data" service.

The problem is that in most of your replies *you* claim authority over defining what is Linked Data related and what is not, while other people here in the forum might have a completely different opinion. I found Harish's announcement sufficiently related to Linked Data so as to be one of the most interesting posts for me for some time. > > >> I'd say we have not even really started with the issue, we've just pushed >> some technology out there, not knowing yet whether it is really useful. > > I disagree, and here are some very basic examples of proof that the utility > (usefulness) and demand (need) for Linked Data are yesterday's topic: > > 1.

Harish mentions in his original post: "The core application is generic - it can consume any kind of rdf/owl data. However, to show case the technology, we dicided to pick one source (crunchbase) to demo the capabilities of the product." In his follow-up he says: "Also, if you are wondering how we are leveraging semweb concepts, here are a few pointers - all entities like companies, investors etc are given uri's - when companies have common investors or are competitors to each other, they are automatically "merged" to create a seamless database The long term objective is to do this across websites - ie harness the web of data that backs the web of pages. Right now for instance, we me can automatically merge data grabbed from crunchbase and data grabbed from linkedin public profiles if the crunchbase person profile has a link to the the linkedin profile. Full support for RDFa and LinkedData is part of the roadmap." So what I read is that he builds an application that uses Linked Data (since it can consume any kind of rdf/owl data). Sufficient for me. Actually I even forwarded the mail to my group to have a look at the demo, because I found it very relevant. > > My response included examples of what's been achieved with Cruncbase data for > a very long time, so I hoped he would see the virtues in doing something > similar such that in classic Linked Data fashion you end up with a richer Web > of Linked Data. So there is already a "classic" Linked Data fashion? What you send (as always) are links to the URI burner of your own company. Which *in my opinion* is much less Linked Data than the application we are discussing. It is just a wrapper around a 3rd party API allowing to convert proprietary data into RDF. Also, accessing the URI burner just for the Facebook example you send takes much longer than Semgel's complete data analysis process, so why should he rely on the RDF data you provide instead of directly accessing the JSON API (which is about as much Linked Data as Facebook's Open Graph, btw) and mapping it to RDF himself? > >> >> Considering comments like yours, I really fear for the community to loose >> its openness and acceptance of differing opinions. > > What is the differing opinion?
