Object Retrieval API

These interfaces represent retrieval of objects associated with a full text article. This resource can also return reference details for an individual object or an entire full text article. The reference metadata response will contain links to the associated Full-Text article.



The following chart shows the Object Retrieval Views.

request
header params
Accept xsd:string
(required)
default: text/xml
options: text/xml, application/json, application/rdf+xml
This represents the acceptable mime types in which the response can be generated. This can also be submitted as the query string parameter "httpAccept". This returns the response in JSON, ATOM, or XML mark-up.
Authorization xsd:string This header field contains the OAuth bearer access token in which the format of the field is "Bearer <token>" (where the token represents the end-user session key). The presence of a bearer token implies the request will be executed against user-based entitlements. The Authorization field overrides X-ELS-Authtoken.
X-ELS-APIKey xsd:string
(required)
This represents a unique application developer key providing access to API resources. This key can also be submitted as the query string parameter "apiKey"
X-ELS-Authtoken xsd:string This represents a end-user session. If provided, this token is used to validate the credentials needed to access content in this resource. This token can also be submitted through the HTTP header "Authorization" or the query string parameter "access_token".
X-ELS-Insttoken xsd:string This represents a institution token. If provided, this key (in combination with its associated APIKey) is used to establish the credentials needed to access content in this resource. This token can also be provided through the query string parameter "insttoken".
X-ELS-ReqId xsd:string This is a client-defined request identifier, which will be logged in all trace messages of the service. This identifier can be used to track a specific transaction in the service's message logs. It will also be returned as an HTTP header in the corresponding response. Note that this should be a unique identifier for the client, and used to track a single transaction.
X-ELS-ResourceVersion xsd:string Represents the version of the resource that should be received.

This represents the acceptable mime types in which the response can be generated. This can also be submitted as the query string parameter "httpAccept". This returns the response in JSON, ATOM, or XML mark-up.
Authorization xsd:string This header field contains the OAuth bearer access token in which the format of the field is "Bearer <token>" (where the token represents the end-user session key). The presence of a bearer token implies the request will be executed against user-based entitlements. The Authorization field overrides X-ELS-Authtoken.
X-ELS-APIKey xsd:string
(required)
This represents a unique application developer key providing access to API resources. This key can also be submitted as the query string parameter "apiKey"
X-ELS-Authtoken xsd:string This represents a end-user session. If provided, this token is used to validate the credentials needed to access content in this resource. This token can also be submitted through the HTTP header "Authorization" or the query string parameter "access_token".
X-ELS-Insttoken xsd:string This represents a institution token. If provided, this key (in combination with its associated APIKey) is used to establish the credentials needed to access content in this resource. This token can also be provided through the query string parameter "insttoken".
X-ELS-ReqId xsd:string This is a client-defined request identifier, which will be logged in all trace messages of the service. This identifier can be used to track a specific transaction in the service's message logs. It will also be returned as an HTTP header in the corresponding response. Note that this should be a unique identifier for the client, and used to track a single transaction.
X-ELS-ResourceVersion xsd:string Represents the version of the resource that should be received.

Object Retrieval API: This represents retrieval of a specific object associated with a full text article, identified by EID (Electronic Identifier). When specifying a view and a supported mime type (XML, JSON, or RDF), the object metadata will be returned instead of the object itself.

Methods
GET simple()

request
header params
Accept xsd:string
(required)
default: */*
options: text/xml, application/pdf, image/jpeg, image/gif, image/png, image/svg, image/tiff, application/vnd.ms-excel, application/postscript, text/mathml, application/excel, application/ppt, application/word, text/plain, application/rtf, video/avi, video/x-flv, audio/mp3, video/mpeg, video/mpeg4, video/quicktime, application/x-tar, application/zip, application/vnd.google-earth.kml+xml, application/vnd.google-earth.kmz
This represents the acceptable mime types in which the response can be generated. This can also be submitted as the query string parameter "httpAccept". This returns the response in JSON, ATOM, or XML mark-up.
Authorization xsd:string This header field contains the OAuth bearer access token in which the format of the field is "Bearer <token>" (where the token represents the end-user session key). The presence of a bearer token implies the request will be executed against user-based entitlements. The Authorization field overrides X-ELS-Authtoken.
X-ELS-APIKey xsd:string
(required)
This represents a unique application developer key providing access to API resources. This key can also be submitted as the query string parameter "apiKey"
X-ELS-Authtoken xsd:string This represents a end-user session. If provided, this token is used to validate the credentials needed to access content in this resource. This token can also be submitted through the HTTP header "Authorization" or the query string parameter "access_token".
X-ELS-Insttoken xsd:string This represents a institution token. If provided, this key (in combination with its associated APIKey) is used to establish the credentials needed to access content in this resource. This token can also be provided through the query string parameter "insttoken".
X-ELS-ReqId xsd:string This is a client-defined request identifier, which will be logged in all trace messages of the service. This identifier can be used to track a specific transaction in the service's message logs. It will also be returned as an HTTP header in the corresponding response. Note that this should be a unique identifier for the client, and used to track a single transaction.
X-ELS-ResourceVersion xsd:string Represents the version of the resource that should be received.

Override for HTTP header Accept, this represents the acceptable mime types for which the response can be generated.
access_token xsd:string Override for HTTP header Authorization, this contains the OAuth bearer access token, where the format of the field is "<token>" (where the token represents the end-user session key). The presence of a bearer token implies the request will be executed against user-based entitlements.

reqId xsd:string Override for HTTP header X-ELS-ReqId, this is a client-defined request identifier, which will be logged in all trace messages of the service. This identifier can be used to track a specific transaction in the service's message logs. Note that this should be a unique identifier for the client, and used to track a single transaction.

META - This alias represents the object metadata associated with the document. This can represent a single object reference or all objects associated with a document, depending upon the resource identifier.



The following chart shows the Object Retrieval META View.



THUMBNAIL - This returns the smallest version of the object, if image



STANDARD - This returns the attachment or, if image, the regular form of the image



HIGH - This returns the highest resolution form of the object, if image
field xsd:string

This alias represents the name of specific fields that should be returned. The list of fields include all of the fields returned in the response payload (see view).

Multiple fields can be specified, delimited by commas.Note that this implies the metadata of an object will be returned.
