Several newly developed methods providing a JSP API into metacat. Most of the new methods were developed to support FGDC metadata.
Some of the other new methods merely provide convenience to the JSP code. New methods include:
nextVersion, getFGDCdistinfo, addDistInfoToFGDC, vectorToHtmlSelect, mapToHtmlSelect, htmlInput, getSessValue, setSessValue, query, getSelectQueryMap,...

Modified method "doMetadataUpload". Improved file type parsing. Also changed call to "upload", to send Integer.MAX_VALUE as the file size,
since file size is not available until read (i.e. "Content-Length", which is available, isn't the same as the individual file sizes)....

Code design document of the login process, as done in the KNB skin.

Change a log level. Sometime it confuses people.

changed web site to use new documentation paths. this break a lot of stuff because metacat won't return the subelements of an xpath query. this will have to be fixed through metacat

Metacat JSP API Additions. The new methods currently only handle inserts of new metadata files and related data files. It also handles instance creation and login support, with
a few convenience methodes intended to be called by a JSP file.
Update and delete support will be added. Also, the new methods currently only handle FGDC metadata files. More XML grammars will be added.

KNP skin customization. Initial checkin of new file. Called by the standard skin javascript protocol of "insertLoginBox()".
This contains a non-modal "Login Form" and account management links. It also contains a web form for inserting a new metacat data package.

Fix bug that if there is a search value is different to others, the query wouold work.

Added a new class called Sitemap that is used to generate a series of XML documents representing the URLs of metacat documents following the sitemap protocol. The Sitemap class extends TimerTask so that it can be scheduled to run once a day or so. New configuration options were added to metacat.properties to control where the sitemaps are written and hw often they are updated. By default we do it once a day, as more often is overkill for search engines....

Added servlet mapping that allows PATHINFO to be passed to the metacat servlet for use in URL handling for READ action.

transfer to value to upper case.

Added new feature to allow metacat documents to be retrieved from a URL that does not use the query url syntax, instead embedding the docid and qformat in the url path, as in this example:
http://localhost:8180/knb/metacat/test.1.1/knb
This format allows clients to read documents without entering a query URL, which will be used in a subsequent step to allow search engines to better index metacat content.

Decreased the debug message priority to 'debug' level for messages when reading an XML document.

Fixed bug that modified query wasn't add.

Add some new constance

This commit is for branch. In this commit the correct ip and user name will be stored in access_log table in replication event. However, it only for Forcereplication. And the test isn't completed yet. This commit is only for future use.

checking in timing print statments

Add a new method to print out more effecient query.

Add new data structure and method to handle query terms which have same search value.

Add a new method to compare the query terms to see if they have same search value.

Get rid of user_owner=public part in access query.

reformatted a bit and removed unneeded code

paging now works well. sped up the caching by using SAX instead of DOM parsing. it seems fast. need some other people to test for me though. the two params needed are 'pagesize' and 'pagestart'. I haven't updated any of the web interfaces to use this, so if you want to try it, you'll have to type in the url the old fashioned way

Add a new overload method - createResultDocument and add a new check for null.

got paging working. metacat also now caches resultsets for users' sessions. the paging is a bit slow, due to some xpath statements. i need to get this optimized now.

Fix bug in advanced search that first surfaced in Java 1.5.0/Tomcat 5.5. Only set the sessid parameter if the sessionId string that is passed in is non-null.

Change "server" to "config.hostname" in config.hostname description.

At Jing's suggestion, added back descriptions for the 'server' and 'httpserver' properties. Since the default values can be used in most cases, the descriptions were added to the table titled 'Other properties in build.properties that you can (but generally need not) change'....

Update metacat installation documentation for 1.7 release.

Initial design document for the SEON data set uploading to metacat.
