HOSS™ – The Semantic Storage

Powered by

The first graph based

storage platform.



Gian Luca Farina Perseu

CEO



What’s HOSS™ :• a complete solution for creating, organizing and publishing semantic

data

• stores and manages data in a schema less data store, allowing complete flexibility of the shape of the data stored

• removes the complexity of managing and publishing semantic data by providing a set of RESTful services, integrated security, a complete publishing model and enterprise features such as persistent caching and reliable message queue for notifications.



What HOSS™ resolves:• According to numerous research reports, organizations are struggling to manage and

leverage unstructured information

• For example: documents, metadata, content, user-generated content, RSS feeds, email, geospatial data, and XML among others

• Unstructured information has one or more of the following characteristics:

• Heterogeneous (different formats, varying standards, irregular lengths, etc.)

• Constantly evolving in ways that may be unanticipated

• Growing exponentially



These characteristics make it difficult to manage unstructured

information using previous technologies, such as relational

databases, which typically expect data that is normalized and

conforms to a pre-defined schema.



What HOSS™ provides:• A simple, consistent web API for storing, managing and retrieving

data

• Flexible, schema-free metadata that allows applications to be easily evolved

• A range of data access and query options enabling easy integration into both new and existing applications

• Platform As A Service or On Premise options for best requirements agree



Solutions with HOSS™ :• Common Repository

• Metadata Catalog

• Geo-spatial storing and localization

• Digital Content Delivery

• Information Intelligence

• Social Applications



Case Study - MuseoTorino:

One of the first GraphDB ( based application in Italy. Use of Web 3.0 rules, applied on the best municipality city heritage collection.

Full Open/Public Data access thru specific APIs.

Why graph based ?



Life is a graph …

Torino

Born, 10 August 1810

Died, 6 June 1861

Lived Position

RIP

1°Cavour’s government (1852-1855)


Cavour Park

Position

1°Cavour’s Italian government (1861)


Govern2° level correlation !!

4° level correlation !!



Semantic ready:• Explicit semantic:

• [Cavour] [died] [Torino]

• [Castello Cavour] [contains body of (vs RIP)] [Cavour]

• Implicit semantic:

• [Palazzo Cavour] [is related to] [Castello di Cavour] (2nd level)

• [Via Cavour] [is related to] [Parco Cavour] [4th level)



Powerful traversing:A Traversal is how you query a Graph, navigating from starting Nodes to related Nodes according to an algorithm, finding answers to questions like “what music do my friends like that I don’t yet own,” or “if this power supply goes down, what web services are affected?”

• Simple traverse: can find all the based on edge property (eg. Social Network)

• All shortest paths: can find multiple paths between the same nodes

• Best shortest paths: can find the single shortest paths between the same nodes

• Dijkstra algorithm: shortest path based on Dijkstra algorithm
