To register image datasets with the ECAI Clearinghouse, you must first create a .tmm (TimeMap Metadata) file to associate with your image. See the Chapter titled "Creating Metadata" for information about this process. Once this process has been completed, invoke the relevant .tmm file in the Editor window in the Metadata Editor. Then press the Register/Upload Metadata to Clearinghouse button on the toolbar.
Unless you have already loggin in in this session, the Metadata Editor will prompt you for your ECAI User name and Password.
If you have specified the correct metadata for your image, the image Registration dialogue should appear.
Note: If the wrong dialogue appears, go back to the Editor window of the Metadata Editor and chack your entries, paying close attention to the dc.format (should be "TimeMap Dataset") and the tm.LocalGIStype and tm.MapObjType elements (should be "ImageFile" and/or "Bitmap").
JPEGs
For JPEGs, choose Raster image file on web server from the dropdown, then enter the URL (i.e. the Internet web address) of the image.
In the Authorisation Password(s) field, enter the password you would like ECAI members to use to access this dataset after they have found it with a Clearinghouse search. At the time of writing, there was a single, generic ECAI password that was in use for this field -- if you don't know it, please contact johnson@acl.archaeology.usyd.edu.au.
When you register metadata in the Clearinghouse, the Metadata Editor will drag any thumbnails, samples and documentation you have associated with your dataset along to the Clearinghouse with the metadata. If you do not want this to occur, unselect the Update documentation and thumbnails option.
Your server may require a User name and Password to allow read access to the image. In this case, enter that User name and Password in the fields at the bottom of the dialogue. Be sure not to supply confidential or full access passwords at this point, as they may be accessible to remote users at some stages of the viewing process.
At this point, you may either register the dataset as new or Update (i.e. completely overwrite) an existing metadata registration.
MRSIDs
For MRSIDs, the process is slightly more complex than for JPEGs. First of all, select MrSID image server from the dropdown (MRSIDs cannot be served over the Internet by a regular web server -- see www.lizardtech.com for information about establishing your own local MRSID server).
If you have not created a connection profile for a MRSID Image server, you can do so by Pressing the New/Edit button and entering the relevant information into the Connection Manager. A profile should look something like this (contact your technical staff for information about your own MRSID server information:
If you intend to register MRSID images served by a third party, you can also create a Connection Manager profile for their MRSID server. You can glean most of the relevant information about their MRSID server from viewing the HTML source code of the web page that displays their image (View > Page Source in Netscape; Edit button or View > Source in Internet Explorer).
For example, when you view a MRSID image served by Felix at the Archaeological Computing Laboratory at this URL ...
... and while the O/S information may have to be guesswork, it is only a choice between Windows and Linux.
If you are serving multiple MRSID images (or your profile refers to a third party that is serving multiple images) the only information that will tend to vary from image to image is the filename of the MRSID image itself. Thus you can create a profile in the Connection Manager for a server and simply enter the name of the MRSID image (always [FILENAME].sid) into the Connection Manager each time you register a new image with the ECAI Clearinghouse.
If you make a mistake with the connection metadata, or your MRSID image does not display correctly when you test it in a Viewer, you can always go and adjust the connection metadata using the ECAI Clearinghouse's online metadata editing facility. Once you have created a Connection Manager profile for your MRSID image, enter other information into the Image registration dialogue as you would for JPEGs (see above).
