Interface TikaCoreProperties

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.

Constant Field Values

TIKA_META_EXCEPTION_PREFIX

static final java.lang.String TIKA_META_EXCEPTION_PREFIX

Use this to store parse exception information in the Metadata object.

Constant Field Values

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.

EMBEDDED_RESOURCE_TYPE_KEY

static final java.lang.String EMBEDDED_RESOURCE_TYPE_KEY

Constant Field Values

ORIGINAL_RESOURCE_NAME

static final Property ORIGINAL_RESOURCE_NAME

CONTENT_TYPE_HINT

static final Property CONTENT_TYPE_HINT

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.
