• SHACL Up with Shapely RDF

    Farragut Center

    Semantic Web Technologies have been rapidly maturing and are already being used for serious commercial work. We introduce, demonstrate, and discuss the significance of an emerging W3C recommendation called SHACL (https://www.w3.org/TR/shacl/) (SHApes Constraint Language). Its primary goal is to provide a way to describe and constrain the contents of RDF Graphs. We describe exactly what SHACL is and give some examples from some of our commercial work with clients; we discuss the interacting roles of an enterprise ontology and RDF Shapes and how they work in concert. We demonstrate a prototype tool that integrates the development of Shapes (with an ontology) and show how constraints can be generated from SHACL in the form of ASK queries. SHACL also plays a role as a UI and API aid. This is an important new standard that helps bridge the gap between an enterprise ontology and different enterprise applications that are based on it. Speakers: Dave McComb and Dan Carey Dave McComb — Dave is President and co-founder of Semantic Arts, a company that has been specializing in the application of semantics to large enterprises for 15 years. He has designed Enterprise Ontologies and helped move them into applications for over a dozen large enterprises in as many industries. He is the author of Semantics in Business Systems. Dan Carey — Dan is an ontologist and data architect with 30 years of consulting experience, 25 of it designing databases, data models, and data strategies with major IT service firms. He has worked primarily for government clients at the federal, state, and local levels. Most recently, he has designed semantic technology products in OWL and RDF to assist in military human resources management, and data exchange standards in OWL and XSD. He holds a bachelor's degree in Applied Physics from Georgia Tech. This meet-up is co-located with Semantic Arts (http://www.semanticarts.com/)’ highly acclaimed four-day class, Designing and Building Business Ontologies (http://semanticarts.com/dbbo-registration). There are a few seats left if you’re interested: http://semanticarts.com/dbbo-registration

  • GeoVoCampDC2013 Day 2

    NSF

    You will need to register through the VoCamp site to attend this event. Please visit http://vocamp.org/wiki/GeoVoCampDC2013 for more details. The Spatial Ontology Community of Practice (SOCoP) along with others are currently planning a GeoVoCamp as follow-up to prior GeoVoCamps including those held in Santa Barbara, Dayton and DC in 2012 and at Santa Barbara CA in 2013. As with previous workshops this will be organized around 3-4 Work Groups. We expect some continuation from prior workshops including work on Ontology Design Patterns and the Descartes Core started on in 2012. We welcome additional topics with geospatial and relating domains, such as in the Earth Sciences. While previous experience in developing ontologies or geo-patterns is useful, it is not required to join the camp and all are welcome to sign up and to join, participate and observe. There is no fee. In Nov, we will continue with terrain and surface network concepts from GeoVoCampDC2012. This is a USGS effort to develop ontologies and ontology patterns useful in multifarious applications, such as environmental modeling and the Earth Sciences. A 2nd topic leverages last year's discussion of water quality, environmental or pollution sites. CUAHSI has expressed an interest in participating and may provide a use case to work on. A 3rd topic concerns possible ontology design patterns for Green Building Architecture which would serve as a follow on to the recent Sustainable Data Community Forum workshop. A 4th topic proposed by George Planansky, Harvard's Center for Geographic Analysis (CGA), is one of ontology patterns to help semantic annotation of maps.If you are interested in any of these or have questions please let us know.

  • Linked Data - Structured Data On the Web with David Wood

    American Psychological Association

    The flexible, unstructured nature of the Web is being extended to act as a global database of structured data. Linked Data is a standards-driven model for representing structured data on the Web that gives developers, publishers, and information architects a consistent, predictable way to publish, merge and consume data. The Linked Data model offers the potential to standardize Web data in the same way that SQL standardized large-scale commercial databases. Linked Data has been adopted by many well-known institutions, including Google, Facebook, IBM, Oracle and government agencies, as well as popular Open Source projects such as Drupal. David will present the Linked Data model in plain, jargon-free language to Web developers, avoiding the overly-academic terminology of the Semantic Web. In his new book David describes practical techniques using everyday tools like JavaScript and Python in detail to allow you to work step-by-step through examples of increasing complexity as you explore foundational concepts such as HTTP URIs, the Resource Description Framework (RDF) and the SPARQL query language. Then you'll use various Linked Data document formats to create powerful Web applications and mashups. This book teaches you how to effectively use emerging Web standards to find, query, use and create structured data on the Web. http://manning.com/dwood/ As a Lotico member you are entitled to 42% discount on the full price of the Linked Data book (eBook and print versions.) if you use the code "13ldev". This code will expire Feb 27, 2013 - offer is valid only at manning.com The event will be held in the offices of the American Psychological Association, which is on First Street NE across from the Union Station Metro (exit at 1st Street).

  • GeoVoCampSOCoP2012 Day 1

    Needs a location

    Introduction Are you a geo-science domain expert, or are you simply interested in helping to build a public semantic web vocabulary? Do you have experience in building ontologies, or want to see how it's done? If any of this is true for you, then you might enjoy attending the free GeoVoCamp at the USGS on Nov 29-30. This two day event is a mini-conference where you get to be part of a team designing new vocabularies for the semantic web. The GeoVoCamp will take place at the USGS National facility Nov 29-30 in Reston VA. The session is organized around 4 Work Groups made up of domain experts, group facilitators and people with semantic/ontological experience. Topics Among the topics of groups being formed is one of topographic mapping & hydrology concepts. This is a USGS effort to develop ontologies and ontology patterns useful in multifarious applications, such as environmental modeling and the Earth Sciences. A 2nd topic will deal with the concept of Site (e.g. ecological site or pollution site) A 3rd topic will deal with a general type of containment schema that involve behavior associated with an inside, an outside, a contained entity, possibly boundaries and contained space. Connections to and use of GeoSPARQL will be considered. A final proposed topic is a group working to expand and flesh out the model of a Semantic Trajectory ontology pattern developed at the Dayton VoCamp to cover a broader range of data such as migrations, animal tracking and shipping. While we will discuss candidates for new geo-pattern, specify them based on real data, and implement them in breakout groups, as time permits we may also refine the geo-patterns from prior VoCamps and employ them as relevant to help in the current topics. Candidates include Path-Movement, Points Of Interest, and Stimulus-Sensor-Observation patterns developed in earlier work. While previous experience in developing geo-patterns and ontologies is useful it is not required to join the workshop and people are welcome to join, participate and observe.
