1 Zentity v2.0 Overview Oscar Naim Sr. Research Program Manager Microsoft External Research

2 What’s Zentity? – Research Output Repository Platform – Hybrid store (triples + relational) Key Features – Semantically rich functionality – Data agnostic – Support for extensibility and interoperability Key Scenario – Repository for all scholarly related byproducts of the research life cycle

3 ZentityPlatform Client Applications Desktop Tools SyndicationInterop Search A platform for building services and tools for research output repositories Papers, Videos, Presentations, Lectures, References, Data, Code, etc. Relationships between stored entities

4 Aims to provide necessary building blocks, tools, and services for creating and managing an organization’s repository ecosystem around research content. Built on top of Microsoft SQL Server 2008 and the ADO.NET Entity Framework and LINQ.Entity Framework LINQ

5 Core data model with extensibility, which can be used to create custom data models, even for domains other than Scholarly Communications Built-in Scholarly Works data model with predefined resources Extensive Search similar to Advanced Query Syntax (AQS)AQS Pluggable Authentication and Authorization Security API Basic Web-based User Interface to browse and manage resources with reusable custom controls (Scholarly Works only) RSS/ATOM, OAI-PMH, AtomPub, SWORD Services for exposing resource information Extensive help with code samples extend the platform by developers

6 Zentity.Core Zentity.ScholarlyWorks Data Model Module Resource Type Scalar Property Navigation Property Inheritance Association

7 Change history management for tracking changes to resource metadata and relationships Various ASP.NET custom controls such as ResourceProperties, ResourceListView, TagCloud, etc. Import/ export BibTex for managing citations Prevent duplicates using the Similarity Match API RDFS parser provides functionality to construct an RDF Graph from RDF XML OAI-PMH to expose metadata to external search engine crawlers OAI-ORE support for Resource Maps in RDF/XML AtomPub implementation for supporting deposits to repository

8 Triple stores -Evolution friendly -Poor performance -No need to model everything in advance -Semantic interpretation at the application level Relational schema -Evolution not so easy -Great opportunities for optimization -Model everything in advance Zentity Platform -Maintain a balance -Try to model the frequently used entities in our app domain -Try to capture the frequently used relationships -Allow for extensibility (Relationships, Properties)

9 Focus on “Resources” Surface “Relationships” as first-class entities through our API Model few relationships explicitly for performance reasons (e.g. “contains”, “author”, etc.) for our Scholarly Communications data model Model key entities explicitly for our Scholarly Communications model Expose the same functionality to arbitrary data models

10 Create a platform for building “research output” repositories An ecosystem of services and tools Build an easy-to-install collection of basic services and tools Extensibility SQL Server 2008, Entity Framework,.NET 4.0, LINQ Zentity Platform (based on the Entity Framework + semantic data model) 3 rd -party services, tools, applications, Zentity SDK Zentity services, Web site, interoperability

11 Source code release Target MS-PL or BSD/Apache 2.0 Full test pass/bug fixes CodePlex Up and running in 1 hour SQL “AdventureWorks” equivalent experience Available on a Windows client (i.e. Windows 7) One-hour Evaluation Visually compelling sample applications Dynamic sample data sets that demonstrate value/prop Well documented Zentity SDK ADO.NET Data Services enhancements ODATA compliant.NET 4.0 Upgrade Provide services layer Enable 3-tier applications (backend, middle ware, client) Enterprise ready Zentity Services
