Get object

GET /object/OBJECT_ID will get the full record of the specified object.

In many cases the fields are pretty self-explanatory but in other cases they are a bit fuzzy. Sometimes you need to know the history of the institution and some of its inner workings in order to understand some of the data. This is because our data is often based on our particular cataloguing preferences and not necessarily universally accepted cataloguing standards for cultural objects. Here is a partial list of those fields with explanations.

accessionmethod describes how the work came to be part of the collection
The list of methods includes Gift, Purchase, Transfer, Bequest, and Commission. This information, along with additional details, is also found in an object's provenance and credit line.

accessionyear describes the year the object was acquired
In some cases it represents the year the object officially became part of the museums collection. In other cases it reflects the year Harvard acquired it. Many objects have accession years that predate the existence of the Fogg Museum (1895), the first museum of the three museums that are part of Harvard Art Museums, and thus can be thought of as being acquired by Harvard itself.

accesslevel describes the accessibility of a record
0 – Restricted. Object record is restricted to certain API keys
1 – Public. Object record is available to all API keys

colors describes the colors programmatically extracted from the primary image of the object
An object may have zero or more colors. The color of each pixel is read and then sorted in to buckets. Brightness and gradient variants are reduced so similar colors group together and to keep the number of buckets under 20. Then the those colors are mapped to the museums' color palette, the CSS3 color listing, and hue names.

percent - is the amount, between the range of 0 to 1, of the color found in the image
color - is the color found in the image
spectrum - is the closest match of the color value to the museums' design color spectrum
css3 - is the closest match to the colors listed in the CSS3 color module specification
hue - is the color value mapped to the name of a hue (Red, Orange, Yellow, Green, Blue, Violet, Brown, Grey, Black, White)

imagepermissionlevel describes the level of image copyright permissions for a record
0 – ok to display images at any size
1 – images have restrictions; display at a maximum pixel dimension of 256px
2 – do not display any images

images describes the images of the object
An object may have zero or more images. As of March 2016, 91% of our objects have at least one image.

baseimageurl - is the primary internet address for the image and is delivered through our default image delivery service
copyright - is the copyright for the image
displayorder - is the preferred sequence number for the image within a group of images in the context of the object record; sequencing is especially important for manuscripts and books; an image with displayorder = 1 can be thought of as the current canonical image for the object
format - is the media type/MIME type of the image (typically image/jpeg)
height - is the height of the image in pixels
idsid - is the unique numeric identifier for the image in the Harvard Digital Repository
iiifbaseuri - is the root of the address for accessing the image through our IIIF image delivery service
imageid - is the numeric unique identifier for the image which can be used to construct a URI to dereference it publiccaption - is a descriptive note about the content of the media often listing information about the view (recto, verso, profile, 3/4 view)
renditionnumber - is the unique name for the image; this often takes the form of a prefix + serial number; the prefix can provide hints as to when, why, and how we made the image
width - is the width of the image in pixels

objectid describes the numeric unique identifier for a record

objectnumber describes the unique identifier for a record
This field is also known as accession number. For information on the structure and meaning of these numbers see the article A Numbers Game.

provenance describes the history of ownership of the work
This field is a record of the history of all the people/institutions who have owned the work from its creation until the present. Whenever possible it documents the legal title to a work at any particular time. This field often contains names of people along with the dates and location of ownership.

rank is a number that is a measurement of how inactive the object is
The number is computed every time the data in the API is refreshed. A number of factors go in to generating the number including membership in the “Collection Highlight” group, total number of page views (since 2009), and date of last page view. A lower number means the object is less active. We use the rank field to sort objects on our Browse Our Collections page. We do this to get the least active objects to rise to the top of search results so more of the collection is seen and used online.

seeAlso is an array of links to alternate machine readable versions of the object
An object many have zero or more of these links. The field structure of seeAlso is modelled on the seeAlso block in the IIIF specification

id - is the URI of the machine readable resource
type - is the type of resource such as IIIF Manifest
format - is the media type/MIME type of the resource (typically application/json)
profile - is the link to the service description for the resource

verificationlevel describes the completeness and vetting status of information in a record
0 - Unchecked. Object information has not been verified for completeness and has not been vetted
1 - Poor. Object information is likely incomplete and has not been vetted
2 - Adequate. Object is adequately described but information may not be vetted
3 - Good. Object is well described and information is vetted
4 - Best. Object is extensively researched, well described and information is vetted

            "text": "This three-handled water jar, or hydria, is of the kalpis type, which has a continuous curving profile and originated c. 500 BCE, perhaps in Athens. The body was hammered out of a single sheet of bronze to which the cast portions—three handles, the foot, and the rim—were joined with solder. The surface of the vessel is largely a greenish gold, which is reminiscent of its original color, although there are extensive areas of a darker greenish gray. \r\n \r\nThe rim (15.7 cm in diameter) features an overhanging band of egg-and-dart molding. Each egg is surrounded by a single raised ridge. Tiny beads encircle the outside of the flattened rim. The foot (15.5 cm in diameter) displays a concave band of tongues, in between each of which is a narrower convex tongue. \r\n \r\nThe side handles, decorated with four concave flutes with rounded ends, rise from circular plates decorated with concave tongues. The vertical handle, circular in section, bears five flutes separated by narrow ridges divided by fine grooves. The top rises from a base plate situated beneath the rim, identical with the plates of the side handles. \r\n \r\nThe base plate is a siren, whose sickle-shaped wings rise up out of her torso and curve inward symmetrically on either side of her head. Each individual feather, rendered in relief, has a fine incised median line, on either side of which are tiny incisions. The siren’s body is also covered with finely incised scales, which have a median line flanked by tiny incisions. The siren’s feet, each bearing three claws, hang vertically from raised edges below the scales and grasp an oval object, from which a seven-petalled palmette, with concave leaves, projects downward. \r\n \r\nAbove the palmette are two antithetical, concave S-shaped volutes, the smaller ends of which curl under the siren’s wings. The spaces between the volutes, the wings, and the tendrils are left open. The volutes’ centers are filled with small hemispherical oculi, which may be silver (1). Two curls descend in relief, curving symmetrically over the shoulders of the siren. \r\n \r\nThis hydria belongs to a class of vessels with sirens adorning the base plate of the vertical handles (2). They begin c. 480 BCE and continue throughout the rest of the fifth century, perhaps even into the first quarter of the fourth century. The shape of the Harvard hydria suggests that it dates between 430 and 400 BCE. The only intact Greek bronze vessel in the Harvard Art Museums' collection, this vase was used to carry and pour water, as the name hydria implies. Its funerary significance may be inferred from the presence of the siren at the base of this handle. Such expensive metal vases were given as prizes in athletic contests and often later contained the cremated ashes of their owners. Such use probably explains the unusually fine state of preservation of this hydria. Harvard's hydria represents the highest quality of late Classical Greek metalwork.\r\n \r\nNOTES:\r\n \r\n1.

The handles and foot are cast, with finer details added by cold working using punches and a tracer tool. The castings each correspond perfectly to faint incised lines pre-dating the surface corrosion, which strongly suggests that they do in fact belong to this vessel. In a few areas, there is a vague correspondence in the corrosion products on the casting and the vessel, which further reinforces the match. Some lead residue at two spots point to the use of lead as the original means of attaching the castings. A gap between the cast foot and the vessel at its bottom, now filled with a modern resin, is the only area imperfectly matched. This is understandable as part of the original fabrication in this less visible location. The volute (3 mm in diameter) centers on either side of the center handle decoration, and the entire chest of the siren shows a thin wash of a white metal. This was analyzed by XRF and determined to be silver. Mercury was detected, but at such a low level that a mercury-silver amalgam process is not clearly indicated.\r\n \r\n \r\nHenry Lie (submitted 2008)",

In a few areas, there is a vague correspondence in the corrosion products on the casting and the vessel, which further reinforces the match. Some lead residue at two spots point to the use of lead as the original means of attaching the castings. A gap between the cast foot and the vessel at its bottom, now filled with a modern resin, is the only area imperfectly matched. This is understandable as part of the original fabrication in this less visible location. The volute (3 mm in diameter) centers on either side of the center handle decoration, and the entire chest of the siren shows a thin wash of a white metal. This was analyzed by XRF and determined to be silver. Mercury was detected, but at such a low level that a mercury-silver amalgam process is not clearly indicated.<o:p></o:p></FONT></FONT></SPAN></P>\r\n<P class=MsoNormal style=\"MARGIN: 0in 0in 3pt\"><SPAN style=\"mso-ascii-font-family: 'Times New Roman'; mso-ascii-theme-font: major-bidi; mso-hansi-font-family: 'Times New Roman'; mso-hansi-theme-font: major-bidi; mso-bidi-font-family: 'Times New Roman'; mso-bidi-theme-font: major-bidi\"><o:p><FONT size=3 face=\"Times New Roman\">&nbsp;</FONT></o:p></SPAN></P>\r\n<P class=MsoNormal style=\"MARGIN: 0in 0in 3pt\"><SPAN style=\"mso-ascii-font-family: 'Times New Roman'; mso-ascii-theme-font: major-bidi; mso-hansi-font-family: 'Times New Roman'; mso-hansi-theme-font: major-bidi; mso-bidi-font-family: 'Times New Roman'; mso-bidi-theme-font: major-bidi\"><o:p><FONT size=3 face=\"Times New Roman\">&nbsp;</FONT></o:p></SPAN></P><SPAN style=\"FONT-SIZE: 12pt; FONT-FAMILY: 'Times New Roman','serif'; mso-ascii-theme-font: major-bidi; mso-hansi-theme-font: major-bidi; mso-bidi-theme-font: major-bidi; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-bidi-language: AR-SA; mso-ansi-language: EN-US; mso-fareast-language: EN-US\">Henry Lie (submitted 2008)</SPAN>"
