Tools to Create a Data Model from Your Corpus

A common challenge when creating a Data Model is to know which metas are in your corpus. There are several ways you can explore your available metas using the Exalead CloudView Data Model.

This task shows you how to:

Create a Data Model from Sample Documents

To save time when creating properties, you can use the Trace all metas option.

Important: Every time you scan your sources, this option saves all these metas to an internal database.
Recommendation: Disable Trace all metas after you have generated the properties you need.

  1. In the Administration Console, go to Index > Data Model.
  2. Under Data model options, select Trace all metas
  3. Click Apply.
  4. Go to the Home page, click Scan for the connector.

    This saves all scanned metas to an internal database.

  5. Go back to Index > Data Model > Classes, click Add properties from traced metas.

    This enables you to select multiple metas to save as properties and optionally, index fields or category facets.

    For an example of creating properties from traced metas, see Create a New Class in the Data Model in the Exalead CloudView Getting Started Guide.

  6. Click Generate properties.
  7. Click Apply.
  8. As you have changed the Index Schema by adding new properties, you need to clear the documents in the build group and re-index your data:
    1. On the Home page, under Indexing, click Clear. Wait for the index to clear its documents.
    2. Under Connectors, click Scan next to your connector.

Store Unprocessed metas

You can save unanalyzed metas to a single csv-encoded output context called metas, and then display them in hit content.

Important: This is a legacy option. Save unanalyzed metas using a dynamic property to store them in a dedicated index field (see Creating Dynamic Properties).
Recommendation: It is more convenient to search for each meta individually.

  1. In the Administration Console, go to Index > Data Model.
  2. Under Data model options, select Store all unprocessed metas.
  3. Click Apply.

These metas are retrievable only. You cannot search them. To search on one of these metas, you must create a Data Model property for it.
