Search Paradigm

The caCORE LexEVS architecture includes a service layer that provides a single, common access paradigm to clients that use any of the provided interfaces. As an object-oriented middleware layer designed for flexible data access, caCORE LexEVS relies heavily on strongly typed objects and an object-in/object-out mechanism.

Line Number

Explanation

4

Creates an instance of a class that implements the LexEVSApplicationService interface. This interface defines the service methods used to access data objects.

7

Construct the QueryOptions Object.

8

Populate the QueryOptions with the desired Coding Scheme.

9

Construct a CodingSchemeVersionOrTag Object.

10

Populate the CodingSchemeVersionOrTag Object with the desired Version.

11

Populate the QueryOptions with the above CodingSchemeVersionOrTag Object.

12

Construct the Query By Example Object and populate it with the desired search critieria. For this example, seach for any 'Entity' with an 'entityCode' attribute equaling 'C1234'.

14

Calls the search method of the LexEVSApplicationService object, along with the QueryOptions.
This method returns a List Collection. This list will contain all of the 'Entity' Objects that match the search critieria, while being further modified by the QueryOptions. It this case, it will return all 'Entity' Objects with an 'entityCode' of "C1234" belonging to the CodingScheme "NCI Thesaurus" Version "09.10d".

Web Services API

The caCORE LexEVS Web Services API enables access to caCORE LexEVS data and vocabulary data from development environments where the Java API cannot be used, or where use of XML Web services is more desirable. This includes non-Java platforms and languages such as Perl, C/C++, .NET framework (C#, VB.Net), and Python.

...

To build the client, use the command 'ant all' from the ./webServiceSoapClient directory.

XML-HTTP API

The caCORE LexEVS XML-HTTP API, based on the REST (Representational State Transfer) architectural style, provides a simple interface using the HTTP protocol. In addition to its ability to be invoked from most Internet browsers, developers can use this interface to build applications that do not require any programming overhead other than an HTTP client. This is particularly useful for developing Web applications using AJAX (Asynchronous JavaScript and XML).

titleNote

When specifying attribute values in the query string, note that use of the following characters generates an error:
[ ] / \ # & %

Distributed LexEVS API

Overview

In place of the existing EVS 3.2 object model, caCORE LexEVS is making a gradual transition toward a pure LexEVS back-end terminology server and exposure of the LexEVS Service object model. caCORE 3.2 and earlier required a custom API layer between external users of the system and the proprietary Apelon Terminology Server APIs. With the transition to LexEVS, caCORE LexEVS can publicly expose the open source terminology service API without requiring a custom API layer.
