Because Interoperability is Everything
MatOnto Alpha 1.5
A Decentralized, Federated and Distributed Data Platform.
MatOnto provides a decentralized, federated and distributed data platform for communities to publish and discover data and analytics that are instantly consumable. The 1.5 alpha release of MatOnto (4/5/2017) is now available for free download! MatOnto is published under AGPL. Visit matonto.org for more information.
This release of the MatOnto Platform includes support for datasets, and new features and bug fixes for the MatOnto Ontology Editor, Mapping Tool and SPARQL Query Editor. We are excited to bring you dataset support for collections of RDF graphs that can be managed and queried independently of other data stored within MatOnto repositories. This new feature includes a UI module for creating and managing datasets as well as dataset integration with the Mapping Tool and the SPARQL Editor. The new 1.5 features include:
A new feature in 1.5, MatOnto Datasets provide collections of RDF graphs that can be managed and queried independently of other data stored within MatOnto repositories.
Datasets consist of a collection of RDF graphs that act as default named graphs or named graphs per the SPARQL 1.1 recommendation for RDF Datasets.
Java and REST services are now available for creating, managing, and querying datasets. The services ensure all operations on the Dataset are isolated to that specific set of RDF graphs.
A new UI module provides capabilities for creating and managing datasets.
- Support added for displaying and editing language tags on string literals.
- Support added for displaying and selecting if a property is functional.
- Support added for importing ontologies from a URL. When adding an import, the editor will confirm the URL is resolvable and reload the ontology with the imported entities.
- The Commits tab now renders a commit history chain with links to view the commit changes.
- Added support for loading spinners over specific UI components when waiting on asynchronous calls to load data. This can be seen in the entity usages block.
- All entity hierarchy trees are now sorted alphabetically.
- When rendering labels for entities in hierarchy trees or detail blocks, a "pretty-print" label is displayed using the
dc:title, or the local name of the IRI in that order.
- The editor now supports passive saving. When an ontology entity is modified, the ontology is automatically saved.
- Modified entities are now highlighted using a modification badge and bold formatting.
- Support added for creating custom Annotation Properties.
- Each entity now displays a list of its
- Integration with MatOnto Datasets provides the capability to upload transformed data to a Dataset.
- Removed the idea of a "Base Class" from the mapping configuration. You now select from a list of classes in an order to create class mappings.
SPARQL Query Editor
- Integration with MatOnto Datasets provides the capability to limit a query operation to a particular Dataset.
- Malformed queries now properly display a message describing the parsing error.
- New feature allows user to download the results of a SPARQL tuple query in CSV, TSV, or Excel format.
