Subject: [goodrelations] GoodRelations Service Update 2009-05-05
	Pre-Announcement
Message-ID: <4A015C8E.7000304@ebusiness-unibw.org>

Dear all:

In the past weeks, we received a lot of valuable suggestions on how to 
improve the GoodRelations vocabulary. We tried to address all issues. 
Attached, please find the change log. A pre-release will be available 
later today.

In case any of the proposed changes would cause unwanted side-effects in 
your applications, please inform me at your earliest convenience.

The most important and the only potentially incompatible changes are that

- gr:description is now deprecated; we suggest using rdfs:comment instead
- gr:isListPrice is now deprecated and replaced by the more powerful 
gr:priceType property

The rest are vocabulary extensions or improvements that help increase 
the compatibility with Semantic Web applications.

Best

Martin


2009-05-05 Change Log
=================
- removed p1 namespace prefix (unused)
- added rdfs:label properties for all elements. For reasons of 
consistency, they are identical with the element identifiers (e.g. 
"BusinessEntity"). Ontologically significant individuals (e.g. days of 
the week) also contain the name of their superclass in parentheses (e.g. 
"Friday (DayOfWeek)").
- removed unused protege namespace prefix
- Expanded the descriptions of hasMaxValue and hasMinValue to indicate that
hasMaxValueFloat/hasMaxValueInteger, 
haxMinValueFloat/hasMinValueInteger, or hasValueFloat/hasValueInteger 
should be used when when specifying values.
- set gr:description to deprecated; use rdfs:comment now instead. This 
provides better tooling support.
- Added PayPal as a PaymentMethod.
- Added DeliveryModePickUp as a DeliveryMethod
- Added DeliveryModeFreight as a DeliveryMethod
- Added DeliveryModeOwnFleet  as a DeliveryMethod
- Added PublicHolidays as a DayOfWeek; This is a placeholder for all 
official public holidays at the LocationOfSalesOrServiceProvisioning. It 
allows specifying the opening hours on public holidays. If a given day 
is a public holiday, this specification supersedes the opening hours for 
the respective day of the week.
- Added gr:hasPOS ObjectProperty. This property states that the 
respective LocationOfSalesOrServiceProvisioning is a point of sale for 
the respective BusinessEntity. It allows linking those two types of 
entities without the need for a particular Offering.
- Added VersionInfo property
- Added terms:license statement http://creativecommons.org/licenses/by/3.0/
- Added rdfs:isDefinedBy statements to all elements
    <rdfs:isDefinedBy rdf:resource="http://purl.org/goodrelations/v1"/>
- Added LINK tag to XHTML document header,
<link rel="meta" type="application/rdf+xml" title="RDF/XML definition 
for the GoodRelations ontology" 
href="http://purl.org/goodrelations/v1.owl" />
- Added note that the return format of the ontology specification is 
determined by content negotiation - in order to get a particular format, 
append .owl or .html to the ontology URI.
- Added hasNAICS datatype property for attaching NAICS codes to 
BusinessEntities
- Addes hasISICv4 datatype property for attaching ISIC Rev. 4 codes to 
BusinessEntities.
- Added cardinality recommendations (constraints) to datatype and object 
properties by extending the rdfs:label elements.
- Added isVariantOf object property for modeling product model variants.
This states that a particular ProductOrServiceModel instance is a 
variant of another ProductOrServiceModel. It is pretty safe to infer 
that the variant inherits all quantitativeProductOrServiceProperties, 
qualitativeProductOrServiceProperties, and 
datatypeProductOrServiceProperties that are defined for the first 
ProductOrServiceModel.

Example:
foo:Red_Ford_T_Model gr:isVariantOf foo:Ford_T_Model
- Set isListPrice to DEPRECATED.

This boolean attribute indicates whether a UnitPriceSpecification is a 
list price (usually a vendor recommendation) or not. TRUE indicates it 
is a list price, FALSE indicates it is not. It is safe to assume by 
default that a UnitPriceSpecification that lacks this attributes is not 
list price.
DEPRECATED. Use gr:priceType property instead.

- Added new datatype property priceType: This attribute can be used to 
distinguish multiple different PriceSpecifications for the same Product 
or Service. It supersedes the former isListPrice property. The following 
values are recommended:

SRP: "suggested retail price" - applicable for all sorts of a 
non-binding retail price recommendations, e.g. such published by the 
manufacturer or the distributor. This value replaces the former 
gr:isListPrice property.

INVOICE: The invoice price, mostly used in the car industry - this is 
the price a dealer pays to the manufacturer, excluding rebates and charges.

- Added explicit namespace prefix in addition to the default:
    xmlns:gr="http://purl.org/goodrelations/v1#"
This may make life easier for ontologies that import GoodRelations. 
Note: Proteg? deletes this statement when you open and save the ontology 
file.

Hello all,

Is there a repository of business descriptions?
Something like a triplestore with a SPARQL endpoint.
This way, finding an online bicycle shop delivering to Tokyo would be
as simple as a SPARQL query.
Or are business owners supposed to host their RDF/XML file on their web server?
In that case, how to find business?
Sorry if this already exists, I couldn't find it on the website.

Keep up the good work.

Hi Nicolas,

we are building one ;-) In the meantime, you can use

http://lod.openlinksw.com/
or
http://sindice.com/

http://sindice.com/search?q=*++%3Chttp%3A%2F%2Fwww.w3.org%2F1999%2F02%2F22-rdf-syntax-ns%23type%3E+%3Chttp%3A%2F%2Fpurl.org%2Fgoodrelations%2Fv1%23BusinessEntity%3E&qt=advanced

But I must war you - you are just a few weeks to early. We are 
fine-tuning large datasets right now, which will include > 1 Mio 
instances. This will take, however, a couple of weeks from now.

So don't be disappointed if as of today, sindice shows just some twenty 
businesses. Also, their crawling is incomplete.

Best
Martin


PS: And yes, please create a description for your own business using the 
annotator tool - five minutes to mark your claims in the Web of Data ;-)

Hallo Martin,

I am now browsing Sindice, and I just found this:
<rdfs:comment rdf:datatype="http://www.w3.org/2001/XMLSchema#string">Art
and Streetwear</rdfs:comment>

"Art and Streetwear" is not very understandable for machines, and
that's one of the most important criterion people will search for.
Semantic can bring a lot here.

So how about letting store owner choose terms from DBpedia ? In the
same way http://faviki.com allows users to tag pages with terms coming
from DBpedia. Maybe a selection of Wikipedia categories could cover
enough to represent all businesses.

Same goes for:
<gr:eligibleRegions
rdf:datatype="http://www.w3.org/2001/XMLSchema#string">DE</gr:eligibleRegions>
Using <http://www4.wiwiss.fu-berlin.de/factbook/resource/Germany>
would make it more semantic and more mashupable.

Is there any reason to have strings instead ?

vlg
Nicolas.

Message-ID: <4A02DFF4.9060407@ebusiness-unibw.org>

Hi Nicolas:

Thanks for your feedback!

I. As for the eligible regions: The gr:eligibleRegions property uses the 
two-character version of ISO 3166-1 (ISO 3166-1 alpha-2) for regions or 
ISO 3166-2 , which breaks down the countries from ISO 3166-1 into 
administrative subdivisions.

This is the most widely used and politically consensual standard for 
describing geo-political regions.

By referring to standards, we keep the conceptual dynamics from other 
domains outside of GoodRelations. Also, it is much easier to export 
RDF/XML from existing standards, because ISO-3166 is very widely used.

The full argument is in the GoodRelations Technical report, sections 
3.2.2. and 3.4.5., available at

http://www.heppnetz.de/projects/goodrelations/GoodRelations-TR-final.pdf

II. As for describing WHAT you are selling, there are multiple options 
in GoodRelations:

a) Use a precise products and service ontology like eClassOWL - with 
that you can say that you are talking of "galvaninzed bolt"s with a 
particular gauge and resistance to corrosion etc.
Pro: Semantically precise, allows for parametric search
Con: Feasible only if your range of products is already classified, 
otherwise you must first classify all items manually.

b) Just make each product an instance of gr:ProductOrService (actually: 
one of its three subclasses) and describe it in natural language.
Pro: Easy to create, even for less structured sources or special things
Con: Not a lot of semantic (though the meta-data of GoodRelations 
provides already a lot of added value - if you know that something is a 
gr:ProductOrService, its price is 50$, and its rdfs:comment field 
contains the word "Guitar", you have a lot more certainty about whether 
this is what you are looking for and regarding its commercial meta-data).

c) Use a proprietary hierarchy and convert that into a products and 
services ontology (details are here:
http://www.heppnetz.de/projects/goodrelations/documentation/vocabulary-dev).
Pro: Often not a lot of extra effort over b), users have access to the 
source hierarchy for navigation and search
Con: Semantic interoperability between multiple hierarchies remains 
difficult.

d) Using dbPedia entries - as you can see in the following paper, there 
are many striking arguments for that, in particular the broad coverage 
(more than 200,000 good categories - 8 times as much as eClassOWL contains).

Hepp, Martin; Siorpaes, Katharina; Bachlechner, Daniel: Harvesting Wiki 
Consensus: Using Wikipedia Entries as Vocabulary for Knowledge 
Management, IEEE Internet Computing, Vol. 11, No. 5, pp. 54-65, Sept-Oct 
2007.
PDF at 
http://www.heppnetz.de/files/hepp-siorpaes-bachlechner-harvesting%20wikipedia%20w5054.pdf

Problems with this approach are that
- it is hard to filter out product categories from other dbPedia URIs 
(on the other hand, we could leave that up to human intelligence at the 
annotation stage). Also, basically everything that is an object could 
serve as a product (someone may offer New York city or the Moon for sale 
- legally problematic, but ontology-wise perfectly correct).
- Lack of formal attributes for describing the products in more detail.
- Difficult to implement for exports from Web shop software, since most 
businesses have not yet classified their products in terms of dbPedia 
URIs. So while ideal for manual descriptions using the GoodRelations 
Annotator, it is not perfect for bulk data exports.
- Mapping to industrial classifications, namely eClassOWL is difficult 
(same as with c)).

But basically we are in perfect agreement and we are already planning to 
add dbPedia URIs as an alternative approach for describing the type of 
product or service in more detail.

In the meantime, you can already do so manually by editing the RDF/XML 
file an attaching a link to the dbPedia URI of your choice.

foo:myProduct rdf:type gr:ActualProductOrServiceInstance
foo:myProduct rdf:type <http://dbpedia.org/resource/TV_set>

However, one must be careful, because the semantics of the dbPedia URI 
for types of products is not necessary that of a class of functionally 
similar objects. dbPedia URIs can be interpreted both with a "topic" 
semantics or with a narrow "class" semantics. If used as a class, does 
<http://dbpedia.org/resource/TV_set> subsume only actual TV sets or also 
user's manuals for TV sets?

But again - we are working on a model for the proper representation.


Best - and thanks for trying and the feedback!

Subject: [goodrelations] =?iso-8859-1?q?Bug_in_Prot=E9g=E9_/_Importing_ont?=
	=?iso-8859-1?q?ologies?=
Message-ID: <4A03E777.2010000@ebusiness-unibw.org>

Dear all:

There seems to be a bug in Prot?g? that may cause irritation when 
importing GoodRelations (and other ontologies). The effect is that if 
you try to import GoodRelations into a new OWL project using the 
official URI "http://purl.org/goodrelations/v1", you will get a Java 
exception.

The reason seems to be that Prot?g? does not explicitly request RDF/XML 
and then gets XHTML (the documentation).

There is an easy fix to that: Simply use the URI of the GoodRelations 
OWL file, i.e.

http://purl.org/goodrelations/v1.owl

(mind the .owl suffix!).

That will do the trick.

The problem is not specific to GoodRelations; we were able to reproduce 
it with several other ontologies that use content negotiation. Since the 
latter is a standard technique, I assume the problem is of general 
relevance.

Attached, please find a few screenshots illustrating the problem.

Best
Martin Hepp

Very nice.  After Yahoo SearchMonkey has been around for a while, things are
now also moving at Google.

 

See:

Subject: [goodrelations] ANN: GoodRelations Service Update 2009-05-05 -
 Please refresh your caches!
Message-ID: <4A13C05A.1020001@ebusiness-unibw.org>

Dear all:
We just released a service update of the GoodRelations ontology for
e-commerce.

The ontology is available at

http://purl.org/goodrelations/v1

If you want to explicitly fetch the OWL file or the HTML documentation,
you may also use

http://purl.org/goodrelations/v1.owl

or

http://purl.org/goodrelations/v1.html

Please replace all local copies of GoodRelations by this new file.

The service update is designed to be fully backwards-compatible. Only a
few changes may require small modifications of current applications or
data sets. Those few potentially incompatible changes are as follows:

- gr:description is now deprecated; we suggest using rdfs:comment instead.
- gr:isListPrice is now deprecated and replaced by the more powerful
gr:priceType property.

The remaining changes are vocabulary extensions or improvements that
help increase the compatibility with Semantic Web applications. For
example, we
- changed cardinality recommendations for opening hours and business
functions, which simplifies the usage of GoodRelations in RDFa;
- added PayPal as a payment method, and
- added labels to all elements.

A complete change log is at

http://tinyurl.com/q8yln9

A big thank you for the many valuable suggestions for improvement!

Best

Martin

Subject: [goodrelations] ANN: GoodRelations - E-Commerce on the Web of Data
 - New Datasets and Applications
Message-ID: <4A13C58B.7080402@ebusiness-unibw.org>

Dear all:

Thanks to the help of several partners, there are now new data sets and 
tools related to the GoodRelations ontology for e-commerce:

*1. OpenEAN data set: 1 million EAN/UPC codes plus respective labels*

The full data set is at

http://openean.kaufkauf.net/id/

Individual commodity descriptions can be retrieved as follows:

http://openean.kaufkauf.net/id/EanUpc_<UPC/EAN>

Example:

http://openean.kaufkauf.net/id/EanUpc_0001067792600

With this data set, Point-of-Sale applications can simply query the 
Semantic Web for the proper labels for a given UPC/EAN code. For 
example, the proper label for the UPC/EAN code 0001067792600 can be 
retrieved as follows:

SELECT ?uri, ?label WHERE {?uri rdf:type 
<http://purl.org/goodrelations/v1#ProductOrServiceModel>. ?uri 
<http://purl.org/goodrelations/v1#hasEAN_UCC-13> 
"0001067792600"^^<http://www.w3.org/2001/XMLSchema#string>. ?uri 
rdfs:label ?label}

Since the data set is already replicated in the Virtuoso LOD data space 
(special thanks to Kingsley Idehen from OpenLink Software!), one can 
simply query the respective SPARQL endpoint, e.g.:

http://lod.openlinksw.com/sparql?default-graph-uri=&query=SELECT+%3Furi%2C+%3Flabel+WHERE+{%3Furi+rdf%3Atype+%3Chttp%3A%2F%2Fpurl.org%2Fgoodrelations%2Fv1%23ProductOrServiceModel%3E.+%3Furi+%3Chttp%3A%2F%2Fpurl.org%2Fgoodrelations%2Fv1%23hasEAN_UCC-13%3E+%220001067792600%22^^%3Chttp%3A%2F%2Fwww.w3.org%2F2001%2FXMLSchema%23string%3E.+%3Furi+rdfs%3Alabel+%3Flabel}&format=text%2Fhtml&debug=on&timeout=

(alternatively, use http://tinyurl.com/qxwrt6)

A big thank you goes to Michael Pfeiffer from  Kaufkauf.net 
(http://www.kaufkauf.net/index.php?l=en) for providing the data and for 
hosting the RDF data set, and to Andreas Radinger and Tobias Ostheim for 
the data conversion!
* 
2. FreeclassOWL: Products and services ontology for the construction and 
building industry

*This ontology defines 4,780 classes, 162 properties, and 1,182 
qualitative values for products and services from the construction and 
building materials domain. All labels are available in up to EIGHT 
languages. FreeclassOWL is compatible with GoodRelations and available 
under a Creative Commons 3.0 License.

*Base URI: *
http://www.freeclass.eu/freeclass_v1
*Ontology: *
http://www.freeclass.eu/freeclass_v1.owl
*Documentation:*
http://www.freeclass.eu/freeclass_v1.html

A big thank you goes to Otto Handle from http://www.inndata.at/ for 
making their Freeclass classification available for the Web of Data, and 
to Andreas Radinger and Tobias Ostheim for the data conversion!
*
3. Extensions / Plug-ins for osCommerce and Joomla/Virtuemart

*There are now working prototypes of export interfaces that allow 
creating GoodRelations data directly from popular Web shop or CMS software.

*a) osCommerce Web Shop Software*

http://code.google.com/p/goodrelations-for-oscommerce/

(An alternative export project for osCommerce is at 
http://triplify.org/Configuration/osCommerce.)

*b)  Joomla/Virtuemart CMS/Shop combo*

http://code.google.com/p/goodrelations-for-joomla/

A big thank you goes to Alex Stolz for his hard work in developing the 
two components!

Also, Intershop recently completed an internal feasibility study and 
prototype of RDFa and RDF/XML export for their Enfinity series. The 
results are unfortunately not yet available to the general public, but 
in case you are an Intershop client with Semantic Web interests, it 
would not hurt to ask them...

Best wishes

Dear all:

When importing GoodRelations in Protege, you must specify the exact file 
location of the ontology, i.e.

http://purl.org/goodrelations/v1.owl

Using the ontology base URI

http://purl.org/goodrelations/v1

does not work and causes an error message.

According to Tania Tudorache, this is not a bug but intended behavior.

Martin Hepp


-------- Original Message -------

This is not a bug. If you import an ontology from a URL, you need to
specify the URL of the owl file. So in case of the GoodRelations
ontology, you need to specify:
http://www.heppnetz.de/ontologies/goodrelations/v1.owl

And that works fine in Protege 3.4.

Tania

Dear all,

I want to publish data from Wikitravel.org (like DBpedia does for
Wikipedia) so I need an ontology to describe tourism information
(hotels, restaurants, spots) with details (address, phone, prices,
services, business hours). I was not able to find any, so far.

Am I right that currently GoodRelations is only for e-commerce and
does not apply to such businesses as hotels, restaurants, and
brick-and-mortar shops?

I am sure you have surveyed existing commerce ontologies, so I am
begging for your expertise: what ontologies exist to describe hotels
and restaurants?

Thank you very much,
Nicolas Raoul

No, GoodRelations can be used (and is intended to be used) for exactly 
those scenarios: You can use it to express that you

- rent cars
- sell pizzas (or meals in general)
- sell boats

For brick-and-mortar-businesses, GoodRelations can be used exactly the 
same way as for pure online shops.

You can specify opening hours, shop locations (e.g. for restaurant 
chains) etc.

For hotels and restaurants: There are specializations based on 
GoodRelations for the Austrian e-tourism sector available at

http://www.ebsemantics.net/doc/

restaurants:
http://www.ebsemantics.net/doc/gastro.owl
accommodations:
http://www.ebsemantics.net/doc/acco.owl

But you can basically use either plain GoodRelations or GoodRelations in 
combination with a suitable hotel or meals ontology for specifying 
touristic offers.

If you have any data samples or, better, real-world data sources, we can 
help you with the respective modeling.

As a first starting point, I recommend looking at gr:BusinessFunctions 
for Sell and Lease.

Best

Martin

Dear Nicolas, all:

Of course, you can also use GoodRelations in combination with eClassOWL 
for describing hotels and restaurants:


A good starting point is the tool for creating basic descriptions for 
any business at

http://www.ebusiness-unibw.org/tools/goodrelations-annotator/

The tool only allows choosing from the first two hierarchy levels of 
eClassOWL, but you could replace the class IDs in the RDF/XML later on 
in order to make the description more specific.

A restaurant could use the eClassOWL 5.1.4 category 2520 (Food and 
services) or one of the following more specific classes:

25-20-01-00 -  Restaurant (service), [ eclass:C_AKG508003-gen ]
25-20-01-01 -  Restaurant with conventional service (service),  [ 
eclass:C_AKG509003-gen ]
25-20-01-02 -  Restaurant with self-service (service), [ 
eclass:C_AKG510003-gen ]
25-20-01-03 -  Cafe (service),   25-20-01-03 [ eclass:C_AKG511003-gen ]
25-20-02-01 -  Bar (service), [ eclass:C_AKG515003-gen ]
25-20-02-02 -  Bar and entertainment restaurant (service) [ 
eclass:C_AKG516003-gen ]
25-20-02-03 - Disco and dance restaurant (service)  [ 
eclass:C_AKG517003-gen ]

The proper gr:BusinessFunction would be gr:ProvideService, since eClass 
classifies restaurants as types of services. (When using an ontology 
that defines particular types of meals, then the proper business 
function would be "sell".)

A hotel could use the eClassOWL 5.1.4 category 2512 (Travel Management) 
or, better, one of the following more specific classes:

25-12-13-01 -  Hotel (travel management),  [ eclass:C_AKG314003-gen ]
25-12-13-02 -  Hotel garni (travel management),    [ 
eclass:C_AKG315003-gen ]
25-12-13-03 -  Inn (travel management),[ eclass:C_AKG316003-gen ]
25-12-13-04 -  Pension (travel management),  [ eclass:C_AKG317003-gen ]

The proper gr:BusinessFunction would be gr:ProvideService, too.

I am happy but confused. The GoodRelations webpage appears very
misleading to me:
1) Motto is "GoodRelations The ontology for E-Commerce"
2) "the representational means required for e-commerce on the Semantic Web"
3) The general term used for businesses/etc is "Web resources"
4) "describing the types of goods and terms and conditions of items
and services offered on the Web": it is not obvious that "on the Web"
refers to "describing" and not to "offered".

The Semantic Web describes the world. The tiny pub near my place will
probably never do any e-commerce, but I want to describe it in the
Semantic Web. I am glad GoodRelations allows me to do it, but why does
it mentions e-commerce everywhere?

Cheers,
Nicolas.

Hi Nicolas:

As soon as any brick-and-mortar business or pub around the corner is 
publishing a one-page description of itself on the Web (or even gets 
listed in a database-driven Web business registry), this business is 
doing e-commerce.

This is the mainstream definition of e-commerce in academia and 
practice: Using the Internet (or other open digital networks) for any 
stage in the business transaction - from search to transactions. There 
are of course different levels of e-commerce, from the the simple 
presentation of features to end-to-end transaction processing. But as 
soon as your business publishes its range of products or services on the 
Web (or even only in the Web of Data), this is e-commerce.

And that is exactly what GoodRelations is designed for: improving search 
and data interoperability for any business that is offering anything on 
the Web.

Hope that clarifies the issue.

Best
Martin

Thank you for the clarification.
According to this definition, all commerces (nearly) do e-commerce. It
seems quite different from most definitions I can find at
http://www.google.com/search?q=define:e-commerce

Let's say my grand-father's grand-father used to sell sausages in 1875
and I want to describe it in RDF in my library, which is not connected
to the Internet. Was he doing e-commerce?

An ontology for medecine does not call itself an e-medecine ontology.
Similarly, an ontology for commerce would probably be better described
as a commerce ontology than an e-commerce ontology, in my opinion.

I think GoodRelations is a much-needed ontology, I hope it will get
adopted by many. I am just afraid that most people reading the main
page will assume it is for online businesses:
http://www.heppnetz.de/projects/goodrelations

Thanks,
Keep up the good work,
Nicolas Raoul.

(including the mailing list in my reply)

Dear Alex:

I see the point - the problem with turning gr:hasEAN_UCC-13 into an 
owl:InverseFunctionalProperty is, as far as I can see, that

1. there is no canonical way of deriving a URI or URN from a given 
EAN/UCC-13 code. At least, I don't know of any. And unless there is an 
authoritative URI for each EAN/UCC-code, you can still not avoid custom 
inferencing.

2. There may be unwanted side-effects (even if rare), because the same 
gr:ProductModel may have multiple EAN/UCC codes, and, more importantly, 
EAN/UCC codes can be attached both to gr:ProductModels and gr:Offerings 
(which is based on how EAN/UPC identifiers are used in the value chain - 
they can be attached to commodity makes and models and to sales units, 
e.g. bunles or variants).

This is why, for the moment, I favor using custom inferencing to link 
all records that

1. Are of the same type (e.g. are both gr:ProductOrServices or both 
gr:Offerings
AND
2. Have the same EAN/UCC.

Note that two instances x and y whith x being an instance of 
gr:ProductOrService and y being and instance of gr:Offering MUST NOT be 
merged into one by owl:sameAs or other axioms, because 
gr:ProductOrService and gr:Offering are disjoint.

Subject: [goodrelations] GoodRelations entity types hit ranks #3, #20,
 and #46 in popularity on PingTheSemanticWeb
Message-ID: <4A1AD6A6.9030104@ebusiness-unibw.org>

Dear all:

Since our recent new vocabularies and data sets are now properly 
included, GoodRelations elements are now among the most popular concepts 
on the Web of Data according to PingTheSemanticWeb:

Rank 3:     gr:ProductOrServiceModel
Rank 20:   gr:BusinessEntity
Rank 46:   gr:QualitativeValue

Only the long established FOAF person and document elements are used 
more frequently:

Rank 1:     http://xmlns.com/foaf/0.1/Person      19, 002, 417
Rank 2:     http://xmlns.com/foaf/0.1/Document     4, 793, 253

Additional, more powerful datasets are under to be released shortly.

Note that there is a lot of room for additional growth. There are 
actually more than 19 million business entities in Europe alone, which 
are perfect candidates for gr:BusinessEntity, and they will each likely 
have anything between a few and several thousand instances of 
gr:Offering and gr:ProductOrServiceSomeInstacesPlaceholder.

Martin
