</p><h3 class="heading-h2"><a name="Introduction" class="anchorpoint"></a>Introduction</h3><p class="paragraph">When in editing mode, you will see a thumbnail of the image at the top under the header "Medium". The overall header above it says "Editing Catalog Record for Medium 9013", with the final number being the unique THL ID for that image.</p><p class="paragraph">Many of the fields in the image cataloging record are controlled vocabulary that are offered as drop down menus from which you select the item you want. If you need a choice which is not offered, then that choice has be to added to the controlled vocabulary to that field. If you have administrative rights, you will see to the right of the item a choice "new photographer", "new quality type", "manage cameras", and the like. You can click on that and easily add a new item to the relevant controlled vocabulary, which will then show up on the drop down list for that field. If you don't have administrative rights, you will have to contact a THL staffer to get it added; if you think you should have such administrative rights, then request them from THL staff.</p><p class="paragraph">The editing interface first shows you all the fields that currently have data, along with the ability to edit them by changing the current data, or adding new data. At the bottom of these fields is an UPDATE button. If you make changes, you must click this UPDATE button to save them. IF YOU DON'T HIT THE UPDATE BUTTON ALL CHANGES WILL BE LOST!!!
</p><h3 class="heading-h2"><a name="Photographer" class="anchorpoint"></a>Photographer</h3><p class="paragraph">Simply choose the photographer's name. In some cases, people may find they are trading cameras back and forth in a team, such that it is unclear just who photographed a given item. Thus, often people may want to attribute a photo to two people. In this case, just add both photographers. There may be a need to attribute a photo to a corporate organization where there is no sense of the individual photographer and there is a team of people who may have photographed any specific photos. In that case, you can request that the named team be added to the controlled vocabulary.
</p><h3 class="heading-h2"><a name="TimePicturewasTaken" class="anchorpoint"></a>Time Picture was Taken</h3><p class="paragraph">This allows the date and time of the photograph to be specified through a series of drop down lists: year, month, date, hour, minute, second.
</p><h3 class="heading-h2"><a name="QualityType" class="anchorpoint"></a>Quality Type</h3><p class="paragraph">This refers to the quality of the photo in terms of both its content, framing, and technical quality. The choices are: unusable, poor, average, good, excellent. There may be a reason to keep a poor quality image due to its unusual content.
</p><h3 class="heading-h2"><a name="CameraModel" class="anchorpoint"></a>Camera Model</h3><p class="paragraph">This specifies the camera manufacturer and model used to take the photography, if known. Since people often won't remember the model, each manufacturer is also listed with an "unknown model".
</p><h3 class="heading-h2"><a name="RecordingNote" class="anchorpoint"></a>Recording Note</h3><p class="paragraph">This is a free text field. Generally, it should be used to…</p><p class="paragraph">This can be used for an explanation about the situation in which the photo was shot, why it was shot, special circumstances, etc.
</p><h3 class="heading-h2"><a name="RecordingOrientation" class="anchorpoint"></a>Recording Orientation</h3><p class="paragraph">This is a drop down list.
</p><h3 class="heading-h2"><a name="PrivateNote" class="anchorpoint"></a>Private Note</h3><p class="paragraph">These notes are private only for the use of the photographer, such as information about how it links to other private documentation, or personal notes about relationships to the people in the image, etc.
</p><h3 class="heading-h2"><a name="Collection" class="anchorpoint"></a>Collection</h3><p class="paragraph">TBA.
</p><h3 class="heading-h2"><a name="Caption" class="anchorpoint"></a>Caption</h3><p class="paragraph">This should be repeatable so that you can have as many captions as you would like.</p><p class="paragraph"><strong class="bold">Caption</strong>: This is limited to a single sentence. In general, these should not be sentences, but rather sentence fragments; though, if there is a good reason, sentences are acceptable. Use sentence case, such that only the first letter is capitalized except for proper nouns and the like. Every image must have a caption – it is the minimum textual description for images – and this must be of the type "General". Additional captions specific to disciplines may also be added, specifying the caption type below. You can also add additional captions of specialized variety in English, or add captions in other languages.</p><p class="paragraph">If you include any Tibetan words in your caption enter the THL Simplified phonetic followed by the THL extended Wylie in parentheses, with the Wylie in italics. Example: Caves in the right wing of the khyung (<em class="italic">khyung</em>) formation.</p><p class="paragraph">Note: catalogers may be tempted to insert references to the place of recording into the caption, such as, “A woman in Lhasa”, “Morning rituals in Sera Monastery”, etc., however, it has to be kept in mind that the location of images is kept track of in the “location” field within the image catalog record, and thus the location of images can be displayed together with captions. Thus references to the location of an image should be kept to a minimum – the information is redundant. Try to make the caption as informative as possible, otherwise, rather than just generic phrases that offer little insight beyond what is obvious to anyone.</p><p class="paragraph"><strong class="bold">Caption Type</strong>: “General”, “Art historical”, etc. The default is “General”. A single picture can have multiple captions either by the same people, or by different people. Each is “typed”, such that one might make captions that are “art historical” which focus on art historical aspects of the image’s content, someone who is examining 1000 photos and ignores everything except the clothes would use "type=clothes" analysis, etc. and so forth. We have to keep track of these “types”, and provide an exhaustive list for people to utilize, or suggest an addition for.</p><p class="paragraph"><strong class="bold">Caption Language</strong>: this is specified from a drop down list of languages.</p><p class="paragraph"><strong class="bold">Caption Creator</strong>: This is the author of caption, and is automatically assigned from the name of the person logged in who creates the caption. There is currently no way to edit this.
</p><h3 class="heading-h2"><a name="Description" class="anchorpoint"></a>Description</h3><p class="paragraph">This is repeatable so that you can have as many descriptions as you like.</p><p class="paragraph"><strong class="bold">Description</strong>: This is limited to one paragraph (up to a page long) describing the content of the image in detail beyond the caption. Images do not require a description, but in many cases this further analytical detail will be advisable. Additional descriptions specific to disciplines may also be added, specifying the description type below. If you include Tibetan words in your description, enter the THL Simplified phonetic followed by the THL extended Wylie in parentheses, with the Wylie in italics. Example: Caves in the right wing of the khyung (<em class="italic">khyung</em>) formation.</p><p class="paragraph"><strong class="bold">Description Type</strong>:</p><p class="paragraph"><strong class="bold">Description Language</strong>:</p><p class="paragraph"><strong class="bold">Description Creator</strong>:

For that reason, we keep its documentation separate so that a number of editorial manuals can refer to it. For anyone writing descriptions, it is essential that you refer to the <a href="/tools/wiki/THL%20Online%20Essay%20Editor%20Manual.html">THL Online Essay Editor Manual</a> for details on how format your text and use the editor.

Note that keywords should not duplicate location (that is, the name of the feature the image is associated with, such as a lake, monastery and so forth), knowledge map categories associated with the image as topics or subjects, and so forth.

</p><h3 class="heading-h3"><a name="PhotographingRecordingLocation" class="anchorpoint"></a>Photographing/Recording Location</h3><p class="paragraph">This reflects the location where the media was first created - i.e. the spot where a photograph was taken, or a video recorded. In general, this is done by opening up the Place Dictionary within a MMS cataloging record, and specifying the place in question. If the place is not in the Place Dictionary, then it needs to be first added into the Place Dictionary so that the MMS can draw upon it.</p><p class="paragraph">However, there will be often be cases when one has a specific GPS point for a photo - frequent for these days of GPS-enabled cameras, and we thus need for the MMS record to record that information.</p><p class="paragraph"><strong class="bold">Coordinates</strong>: Use if relevant, and if the recording location is a point without a gazetteer entry. Otherwise, the Gazetteer will provide the coordinates. If a GPS reading has been taken at the point of recording, the result may be in degrees or UTM (Universal Transverse Mercator – metric units)</p><p class="paragraph"><strong class="bold">Degrees</strong>: Use this section if the coordinates are in Degrees.
</p><ul class="star"><li>East/West Longitude: Specify here whether the reading is in East or West longitude.</li>
<li>Longitude (X) Degrees:</li>
<li>Longitude (X) Minutes: Sometimes a GPS reading will have minutes followed by a decimal point. In the case of a reading like 31°41.354', "41.354" should be entered for minutes.</li>
<li>Longitude (X) Seconds:</li>
<li>Longitude (X) Decimal: This is for decimal degrees when the value is degrees followed immediately by a decimal point, not a value in seconds. This is the value that is the right of the decimal. In the case of 31.68923°, the value to be entered here is "68923".</li>
<li>North/South Latitude: Specify here whether the reading is in North or South latitude.</li>
<li>Latitude (Y) Degrees:</li>
<li>Latitude (Y) Minutes: Sometimes a GPS reading will have minutes followed by a decimal point. In the case of a reading like 31°41.354', "41.354" should be entered for minutes.</li>

In the case of 31.68923°, the value to be entered here is "68923".</li></ul><p class="paragraph"><strong class="bold">UTM</strong>: Use this if the coordinates are in UTM (metric units). The figures will generally be a 6 or 7-digit number.
</p><ul class="star"><li>UTM Zone: For example the zone value for the Porong region of Tibet is "45".</li>

<li>Elevation:</li>
<li>Units: This refers to the units in which the elevation is measued, for example meters or feet.</li>
<li>Orientation: This refers to the orientation from which a photograph was taken.</li></ul><p class="paragraph"><strong class="bold">Administrative</strong>: This is the location where the photograph was taken in terms of the national administrative hierarchy scheme. It needs to be drawn from the Place Dictionary.</p><p class="paragraph"> <strong class="bold">Spot feature (point of interest)</strong>: This is for a specific building, etc. Note: There is a potentially misleading relationship between spot features and administrative features in this entry form. For instance if a school is determined to be in skyid thang Township but is not located in any particular village, the school will appear as an option as if it were at the same level as a village in skyid thang.</p><p class="paragraph"><strong class="bold">Notes</strong>: Notes on the recording location.</p><p class="paragraph"><strong class="bold">Cultural</strong>: This is the location where the photograph was taken in terms of the cultural hierarchy scheme.
