RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications.
This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes. This graph view is the easiest possible mental model for RDF and is often used in easy-to-understand visual explanations. The RDF 1.

Enter search term. Catalogue search. This data service acts as a contribution to the worldwide information infrastructure and is a prerequisite for modern commercial and non-commercial web services. By offering RDF as an export format, we facilitate subsequent use of our data for users and user groups with no knowledge of bibliographic formats.
The Linked Data Service is continually being developed further and optimised at technical, content-related and organisational levels.

How the different approaches compare? RDF is an abstract knowledge representation model that does not differentiate data from metadata. This prevents the extension of an existing model with statement-level metadata annotations like certainty scores, weights, temporal restrictions, and provenance information like if this was a manually modified annotation.
Several approaches discussed on this page mitigate the inherent lack of native support for such annotations in RDF. However, they all have certain advantages and disadvantages, which we will look at below. Reification means expressing an abstract construct with the existing concrete methods supported by the language. The RDF specification sets a standard vocabulary for representing references to statements like:.
RDF 1.1 Concepts and Abstract Syntax
We want the RDF that we make available to be as useful as possible. In practice, there are various principles that help in satisfying these conditions. These methods will abstract out the identifier from a webpage describing it, and will let you change the URLs for your website later without affecting the RDF. Commonly debated in the Linked Data community is the issue of how to deal with URIs that are used to identify abstract concepts resources rather than web documents.

Semantic Web technologies are emerging as an increasingly important approach to distribute and integrate scientific data. RDF is a core part of semantic web standards. As an extension of the existing World Wide Web , the semantic web attempts to make it easier for users to find, share, and combine information. PubChem users have frequently expressed interest in having a downloadable database.
Together these tools enable the schema-less database access and query. The RDF data on the PubChem FTP site is arranged in such a way that you only need to download the type of information in which you are interested, thus allowing you to avoid downloading parts of PubChem data you will not use. For example, if you are just interested in computed chemical properties, you only need to download PubChemRDF data in the compound descriptor directory.
As depicted in Figure 1 , the PubChemRDF content includes a number of semantic relationships, such as those between compounds and substances, the chemical descriptors associated with compounds and substances, the relationships between compounds, the provenance and attribution metadata of substances, and the concise bioactivity data view of substances.
Whenever possible, pre-existing ontological frameworks were used to semantically describe information available in the PubChem archive , rather than creating new ones. However, in some cases, no suitable types or relations were defined in standard ontologies, and a PubChem vocabulary was created to define these terms. Adoption of these core ontologies helps to ensure that the mapping of chemical and biological information is compatible across multiple Semantic Web resources.

So far, so good. However, it looks as though I have the choice of not stating that it is an E41, or of connecting the E41 to its string value via a property which is nowhere defined in the CRM:. The CRM definition gives strings as examples of E41, which implies that the first form is acceptable. However, my instinct says that it is wrong to finesse the fact that it is an E41 in this way.
Whichever approach is correct, I am struck by the absence of a primer which says, in straightforward terms, “this is how you encode CRM concepts in RDF”. If it exists and I have simply missed it, please point me in its direction and I will spread the word We have often discussed it, but I am not sure if we have written a guideline, and it is not in the right place, or if we have only exchanged e-mails about it.

The copyright holders make no representation about the suitability of the specification for any purpose. It is provided “as is” without expressed or implied warranty. The Publishing Requirements for Industry Standard Metadata PRISM specification defines a standard for interoperable content description, interchange, and reuse in both traditional and electronic publishing contexts.
Beyond those recommendations, it defines a small number of XML namespaces and controlled vocabularies of values, in order to meet the goals listed above.

This note is intended as a 1-page introduction to RDF, aimed at software developers and technically oriented people having a some familiarity with XML and data structures in computer programs. The graph contains nodes, and arcs that connect the nodes. The graph nodes and arcs are labelled using URIs . It also turns out that a relational data model is also easily mapped onto this form, with a node corresponding to a table row or primitive value, and an arc corresponding to a column identifier.
For comparison, the data model that underlies XML is an annotated tree, with XML elements corresponding to nodes of the tree, and XML attributes being annotations applied to some node. This graph based model for RDG data is very flexible, deriving indirectly from a long history of research into knowledge representation Semantic Nets, Conceptual Graphs, etc. It allows arbitrarily complex data to be represented in a form with a very simnple, uniform ujnderlying structure, making it potentially accessible to a range of general purpose RDF processing tools.
It can also be easily applied to much more prosaic purposes. The basic RDF syntax can be rather cumbersome, but if one assumes schema-aware RDF processing or a special-purpose processor , it is possible to design a reasonably neat RDF-compatible form of XML for a typical application.

They work very similarly to the bookmarks, although the fields will be different in each case.

RDF technologies encompass data exchange formats, query languages, and various vocabularies and ontologies [ 1 ]. RDF technologies provide the basis for data integration of heterogeneous data sources as well as for the semantic description of resources in terms of assertions on the properties of these resources and relationships among them. RDF technologies integrate ideas for knowledge representation commonly used by Database and Artificial Intelligence communities, e.

Written by Robin Bloor, posted on Inside Analysis. In a twist that has inevitable written all over it, the database industry has at last begun to take heed of the power of consumerization. The once mighty RDBMS is now obliged to make room for an emerging and increasingly important partner in the data center: the graph database. There are all kinds of graph databases and projects on the market right now, and most of them are purpose-built for a particular workload or platform.
Some technologies are not even databases at all, but rather graph analytics engines that pull data from any convenient source, even Hadoop, and analyze it in the graph engine. Twitter developed its graph database in house and released it as FlockDB to the open source community. Twitter designed it specifically to store relationships and activity between users.
