Media | Index and Indexed Search
Media Index allows you to search using the central index, which comprises both data storage and a query engine. The index receives its data from the original data sources — generally, the databases of multiple asset management systems, including Interplay Production, MAM, and iNEWS — and then pushes the data to the service that does the indexing. This allows the index to continuously sync to the database.
The value of searching the central index lies in how it indexes databases in multiple zones and gives you quick access to all of the media stored in distributed systems for your organization, including both local and remote assets. You can focus your search by adding filters for any metadata included in the index. And since a search using Media Index queries the central index and not the database itself, searches do not affect the performance of the MediaCentral system or the underlying Interplay Production engines.
You need to use an Advance license to use the indexed search and to access the central index when you are connecting to multiple systems within your MediaCentral environment. However, if you have only one system in the index and this system is your local system, and you use a Base license for the system type of the index, then you can use Media Index with a Base license.
If your MediaCentral Platform configuration includes Media Index, federated search is the default search method. You can change this by selecting indexed search from the Pane Menu. The search type selection persists for each user.
Media | Index and Interplay Production
Indexed search maps Interplay Production properties to Media Index criterion fields. The following table describes how Media Index categorizes some common Interplay Production properties:
Interplay Production Property | Media Index Field |
Name | Name |
Created By | Creator |
Creation Date | Created |
Modified Date | Modified |
Changed By | Modifier |
Start | Start |
End | End |
Duration | Duration |
Comments | Description |
Mime Type | Asset type |
Media | Index and Interplay MAM
The indexed search in MediaCentral UX maps Interplay MAM attributes to Media Index criterion fields. Most MAM attributes correspond to Media Index, but some mappings require additional information. You can click the “Show mapping info” link on the title bar of the Sync Service Administrator to see information on mapping of Interplay MAM attributes to Media Index criteria.
If you have administrator privileges for MediaCentral, you can sign in to MediaCentral UX and view the complete mapping information in the Media | Index > Indexes view.
The following table describes how Media Index categorizes Interplay MAM base information:
Interplay MAM Information | Media Index Field |
Prefix.ClassName. The prefix is “sequence” for EDL classes and “asset” for object classes — for example, sequence.EDL and asset.VIDEO. | Type |
SYSTEMID | SystemID |
The following table describes how Media Index categorizes some common Interplay MAM attributes:
Interplay MAM Attribute | Media Index Field |
MAINTITLE | Name |
REGISTRATION_USERLOGIN | Creator |
MODIFICATION_USERLOGIN | Modifier |
REGISTRATION_DATETIME. If REGISTRATION_DATETIME is empty, the values of the REGISTRATION_DATE and REGISTRATION_TIME attributes are combined. | Created |
MODIFICATION_DATETIME. If MODIFICATION_DATETIME is empty, the values of the MODIFICATION_DATE and MODIFICATION_TIME attributes are combined. | Modified |
/api/mam/proxy/forresource?id=interplay-mam:{SYSTEMID}:1|thumb|{DMGUID} | ThumbnailURL |
DESCRIPTION | Description |
For object classes (asset types): SYSTEM_SOC_TC For EDL classes (basic sequence types): • Video: 00:00:00:00 (NDF) or 00;00;00;00 (DF) • Audio: 00:00:00.000 | startTC |
For object classes (asset types): SYSTEM_EOC_TC For EDL classes (basic sequence types): SYSTEM_DURATION_TC | endTC |
SYSTEM_DURATION_TC The value is taken from the SYSTEM_DURATION_UNITS or SYSTEM_DURATION (as fallback) attributes. Every time when SYSTEM_DURATION_UNITS or SYSTEM_DURATION are changed, SYSTEM_DURATION_TC is set. | durationTC |
All other MAM attributes are sent as Custom attributes with prefix “com.avid.mam.” followed by the MAM attribute name in Media Index (for example, com.avid.mam.asset_type).
In MCS v2.6 and later, you can search for Interplay MAM assets that include multi-value metadata. Multi-value metadata contain several keywords assigned to a single media object that are combined as a multi-value attribute. For more information, see the Avid Interplay MAM Desktop User’s Guide.
