```
public interface TikaCoreProperties
```
Contains a core set of basic Tika metadata properties, which all parsers will attempt to supply (where the file format permits). These are all defined in terms of other standard namespaces. Users of Tika who wish to have consistent metadata across file formats can make use of these Properties, knowing that where present they will have consistent semantic meaning between different file formats. (No matter if one file format calls it Title, another Long-Title and another Long-Name, if they all mean the same thing as defined by DublinCore.TITLE then they will all be present as such) For now, most of these properties are composite ones including the deprecated non-prefixed String properties from the Metadata class. In Tika 2.0, most of these will revert back to simple assignments.

Since:

Apache Tika 1.2

- Field Detail
  - TIKA_META_PREFIX
```
static final java.lang.String TIKA_META_PREFIX
```
    Use this to prefix metadata properties that store information about the parsing process. Users should be able to distinguish between metadata that was contained within the document and metadata about the parsing process. In Tika 2.0 (or earlier?), let's change X-ParsedBy to X-TIKA-Parsed-By.

  - TIKA_META_EXCEPTION_WARNING
```
static final Property TIKA_META_EXCEPTION_WARNING
```
    Use this to store exceptions caught during a parse that are non-fatal, e.g. if a parser is in lenient mode and more content can be extracted if we ignore an exception thrown by a dependency.
  - TIKA_META_EXCEPTION_EMBEDDED_STREAM
```
static final Property TIKA_META_EXCEPTION_EMBEDDED_STREAM
```
    Use this to store exceptions caught while trying to read the stream of an embedded resource. Do not use this if there is a parse exception on the embedded resource.

    This is currently used to identify Content-Type that may be included within a document, such as in html documents (e.g. ) , or the value might come from outside the document. This information may be faulty and should be treated only as a hint.
