Guidelines

OpenURL query problems and deposits , there is no DOI: in a DOI value

Deposits 2 or more deposits can be running simultaneously, A temp file is created using the HTTP fname parameter … prevents two files with the same name from being deposited at the same time

Queries Try to avoid many requests with only one query (group in 10+) Upload very large (1000+) queries using asynchronous query interface

OpenURL Query Format DON’T : id=doi:10.1061/(ASCE)0893-1321(2002)15:4(125)

Reduce dependence on mddb.xml pre-filtering, submit more queries

DO : id=10.1061/(ASCE)0893-1321(2002)15:4(125)

XSD, operation=doXSDMDUpload : DTD, operation=doMDUpload


Programming - Perl

#!/usr/bin/perl -wuse strict;use LWP::UserAgent;use URI::Escape;require HTTP::Headers;

my $h = HTTP::Headers->new;$h->header('Content-Type' => 'application/x-www-form-urlencoded'); my $user=“XXXX";my $pass=“yyyyy";my $query="00218561|||50|16|4713|||1| ….

my $verysafe = uri_escape($query, "| \n");

Query as an HTTP POST


my $user_agent = new LWP::UserAgent;$user_agent->agent(“Your agent name".$user_agent->agent);$user_agent->timeout(360);

my $req = new HTTP::Request 'POST', 'http://mddb2.crossref.org /query/xref.cgi', $h;$req->content("usr=$user&pwd=$pass&db=mddb&qdata=$query");

# Send query to the servermy $response;$response = $user_agent->request($req);

Query as an HTTP POST cont.

uploadFileOpts[0] = new HTTPClient.NVPair ("fname",XMLFile);

HTTPClient.NVPair[] ct_hdr = new HTTPClient.NVPair[1]; byte[] uploadBytes;

Deposit as an HTTP POST

Down load sample code from our site

HTTPClient.HTTPConnection httpConn = new HTTPClient.HTTPConnection (host,port);uploadBytes = HTTPClient.Codecs.mpFormDataEncode (uploadOpts,uploadFileOpts,ct_hdr);HTTPClient.CookieModule.setCookiePolicyHandler(null); HTTPClient.HTTPResponse httpResp = null;

httpResp = httpConn.Post ("/servlet/deposit?login_id=" + username + "&login_passwd=" + password,uploadBytes,ct_hdr); ….

Programming - VB

Set WinHttpReq = New WinHttpRequest (need winhttp50sdk.exe)

WinHttpReq.SetTimeouts 0, 60000, 60000, 300000

WinHttpReq.Open "GET", _ "http://mddb2.crossref.org/query/xref.cgi?usr=" + username.Text + _ "&pwd=" + password.Text + "&area=" + area + "&fuzzy=true&type=" + _ “operation + "&qdata=" + qData” , False

WinHttpReq.Send

results = WinHttpReq.ResponseText

Query as an HTTP GET
