Grid-ML XML Schema Viewer

A lightning fast and intuitive tool for viewing and searching XML Schemas.

Grid-ML XML Schema Viewer is a fast and intuitive tool for viewing and searching W3C XML Schemas (XSD). It searches names, comments and enumeration values. Once found, the data path and its definition can be easily copied and pasted into any document or spreadsheet.

MISMO Model Viewer

When the target word or phrase has multiple possible matches, Grid-ML shows the locations of all data items in an uncluttered, hierarchical schema view. The business analyst can quickly drill down to the relevant locations to search deeper. The search results can be filtered to show just container elements, data point elements, attributes, and enumerations. The search can also be set to include or exclude data types and definitions.

Data mapping

Working with large data models can be frustrating. We get it.

Nowadays, it is common to find data exchange models with thousands of data points. That is more than any person can learn. Even the most experienced analysts have difficulty remembering how each piece of data is represented in a given industry standard.

Business analysts spend a considerable amount of time searching various data models to understand how the data is structured, how it relates to previous versions of a model, and how to map the information to their systems.

Those factors lead to increased development costs, hard-to-find errors, unexpected rework, and project delays.

Generic tools are not adequate.

Full-blown XML editors like XMLSpy® and Sparx EA are good for creating schemas but are not aimed to help you search and discover. The graphical view is not adequate for large schemas and the XML view is too technical for most business users.

Likewise, MS Excel is not setup for dealing with hierarchical data, the search process is slow, and the search results are difficult to visualize.
